 When the client raises an `Error` that originated at the HTTP layer, like a `ConnectionError` or `TimeoutError`, a `meta` object is often attached to the error object that includes metadata useful for debugging, like request and response information. Because this can include potentially sensitive data, like authentication secrets in an `Authorization` header, the client takes measures to redact common sources of sensitive data when this metadata is attached and serialized.

+===== Drop testing artifacts from npm package
+
+Tap, the unit testing tool used by this project, was recently upgraded and started writing to a `.tap` directory. Since tests are run prior to an `npm publish` in CI, this directory was being included in the published package and bloating its size.

+[discrete]
+===== Request retries are more polite
+
+https://github.com/elastic/elastic-transport-js/releases/tag/v8.6.0[`@elastic/transport` v8.6.0] was released, which refactored when and how failed requests are retried. Timed-out requests are no longer retried by default, and retries now use exponential backoff rather than running immediately.

+
+`@elastic/transport` https://github.com/elastic/elastic-transport-js/releases/tag/v8.4.0[version 8.4.0] introduces enhanced measures for ensuring that request metadata attached to some `Error` objects is redacted. This functionality is primarily to address custom logging solutions that don't use common serialization methods like `JSON.stringify`, `console.log`, or `util.inspect`, which were already accounted for.

+
+[discrete]
+===== Drop old typescript definitions
+
+*Breaking: Yes* | *Migration effort: Medium*
+
+The current TypeScript definitions will be removed from the client, and the new definitions, which contain request and response definitions as well will be shipped by default.
+
+[discrete]
+===== Drop callback-style API
+
+*Breaking: Yes* | *Migration effort: Large*
+
+Maintaining both API styles is not a problem per se, but it makes error handling more convoluted due to async stack traces.
+Moving to a full-promise API will solve this issue.
+
+[source,js]
+----
+// callback-style api
+client.search({ params }, { options }, (err, result) => {
+ console.log(err || result)
+})
+
+// promise-style api
+client.search({ params }, { options })
+  .then(console.log)
+  .catch(console.log)
+
+// async-style (sugar syntax on top of promises)
+const response = await client.search({ params }, { options })
+console.log(response)
+----
+
+If you are already using the promise-style API, this won't be a breaking change for you.
+
+[discrete]
+===== Remove the current abort API and use the new AbortController standard
+
+*Breaking: Yes* | *Migration effort: Small*
+
+The old abort API makes sense for callbacks but it's annoying to use with promises
+
+[source,js]
+----
+// callback-style api
+const request = client.search({ params }, { options }, (err, result) => {
+ console.log(err) // RequestAbortedError
+})
+
+request.abort()
+
+// promise-style api
+const promise = client.search({ params }, { options })
+
+promise
+  .then(console.log)
+  .catch(console.log) // RequestAbortedError
+
+promise.abort()
+----
+
+Node v12 has added the standard https://nodejs.org/api/globals.html#globals_class_abortcontroller[`AbortController`] API which is designed to work well with both callbacks and promises.
+[source,js]
+----
+const ac = new AbortController()
+client.search({ params }, { signal: ac.signal })
+  .then(console.log)
+  .catch(console.log) // RequestAbortedError
+
+ac.abort()
+----
+
+[discrete]
+===== Remove the body key from the request
+
+*Breaking: Yes* | *Migration effort: Small*
+
+Thanks to the new types we are developing now we know exactly where a parameter should go.
+The client API leaks HTTP-related notions in many places, and removing them would definitely improve the DX.
+
+This could be a rather big breaking change, so a double solution could be used during the 8.x lifecycle. (accepting body keys without them being wrapped in the body as well as the current solution).
+
+To convert code from 7.x, you need to remove the `body` parameter in all the endpoints request.
+For instance, this is an example for the `search` endpoint:
+
+[source,js]
+----
+// from
+const response = await client.search({
+  index: 'test',
+  body: {
+    query: {
+      match_all: {}
+    }
+  }
+})
+
+// to
+const response = await client.search({
+  index: 'test',
+  query: {
+    match_all: {}
+  }
+})
+----
+
+[discrete]
+===== Migrate to new separate transport
+
+*Breaking: Yes* | *Migration effort: Small to none*
+
+The separated transport has been rewritten in TypeScript and has already dropped the callback style API.
+Given that now is separated, most of the Elasticsearch specific concepts have been removed, and the client will likely need to extend parts of it for reintroducing them.
+If you weren't extending the internals of the client, this won't be a breaking change for you.
+
+[discrete]
+===== The returned value of API calls is the body and not the HTTP related keys
+
+*Breaking: Yes* | *Migration effort: Small*
+
+The client API leaks HTTP-related notions in many places, and removing them would definitely improve the DX.
+The client will expose a new request-specific option to still get the full response details.
+
+The new behaviour returns the `body` value directly as response.
+If you want to have the 7.x response format, you need to add `meta : true` in the request.
+This will return all the HTTP meta information, including the `body`.
+
+For instance, this is an example for the `search` endpoint:
+
+[source,js]
+----
+// from
+const response = await client.search({
+  index: 'test',
+  body: {
+    query: {
+      match_all: {}
+    }
+  }
+})
+console.log(response) // { body: SearchResponse, statusCode: number, headers: object, warnings: array }
+
+// to
+const response = await client.search({
+  index: 'test',
+  query: {
+    match_all: {}
+  }
+})
+console.log(response) // SearchResponse
+
+// with a bit of TypeScript and JavaScript magic...
+const response = await client.search({
+  index: 'test',
+  query: {
+    match_all: {}
+  }
+}, {
+  meta: true
+})
+console.log(response) // { body: SearchResponse, statusCode: number, headers: object, warnings: array }
+----
+
+[discrete]
+===== Use a weighted connection pool
+
+*Breaking: Yes* | *Migration effort: Small to none*
+
+Move from the current cluster connection pool to a weight-based implementation.
+This new implementation offers better performances and runs less code in the background, the old connection pool can still be used.
+If you weren't extending the internals of the client, this won't be a breaking change for you.
+
+[discrete]
+===== Migrate to the "undici" http client
+
+*Breaking: Yes* | *Migration effort: Small to none*
+
+By default, the HTTP client will no longer be the default Node.js HTTP client, but https://github.com/nodejs/undici[undici] instead.
+Undici is a brand new HTTP client written from scratch, it offers vastly improved performances and has better support for promises.
+Furthermore, it offers comprehensive and predictable error handling. The old HTTP client can still be used.
+If you weren't extending the internals of the client, this won't be a breaking change for you.
+
+[discrete]
+===== Drop support for old camelCased keys
+
+*Breaking: Yes* | *Migration effort: Medium*
+
+Currently, every path or query parameter could be expressed in both `snake_case` and `camelCase`. Internally the client will convert everything to `snake_case`.
+This was done in an effort to reduce the friction of migrating from the legacy to the new client, but now it no longer makes sense.
+If you are already using `snake_case` keys, this won't be a breaking change for you.
+
+[discrete]
+===== Rename `ssl` option to `tls`
+
+*Breaking: Yes* | *Migration effort: Small*
+
+People usually refers to this as `tls`, furthermore, internally we use the tls API and Node.js refers to it as tls everywhere.
+[source,js]
+----
+// before
+const client = new Client({
+  node: 'https://localhost:9200',
+  ssl: {
+    rejectUnauthorized: false
+  }
+})
+
+// after
+const client = new Client({
+  node: 'https://localhost:9200',
+  tls: {
+    rejectUnauthorized: false
+  }
+})
+----
+
+[discrete]
+===== Remove prototype poisoning protection
+
+*Breaking: Yes* | *Migration effort: Small*
+
+Prototype poisoning protection is very useful, but it can cause performances issues with big payloads.
+In v8 it will be removed, and the documentation will show how to add it back with a custom serializer.
+
+[discrete]
+===== Remove client extensions API
+
+*Breaking: Yes* | *Migration effort: Large*
+
+Nowadays the client support the entire Elasticsearch API, and the `transport.request` method can be used if necessary. The client extensions API have no reason to exist.
+[source,js]
+----
+client.extend('utility.index', ({ makeRequest }) => {
+  return function _index (params, options) {
+    // your code
+  }
+})
+
+client.utility.index(...)
+----
+
+If you weren't using client extensions, this won't be a breaking change for you.
+
+[discrete]
+===== Move to TypeScript
+
+*Breaking: No* | *Migration effort: None*
+
+The new separated transport is already written in TypeScript, and it makes sense that the client v8 will be fully written in TypeScript as well.
+
+[discrete]
+===== Move from emitter-like interface to a diagnostic method
+
+*Breaking: Yes* | *Migration effort: Small*
+
+Currently, the client offers a subset of methods of the `EventEmitter` class, v8 will ship with a `diagnostic` property which will be a proper event emitter.
+[source,js]
+----
+// from
+client.on('request', console.log)
+
+// to
+client.diagnostic.on('request', console.log)
+----
+
+[discrete]
+===== Remove username & password properties from Cloud configuration
+
+*Breaking: Yes* | *Migration effort: Small*
+
+The Cloud configuration does not support ApiKey and Bearer auth, while the `auth` options does.
+There is no need to keep the legacy basic auth support in the cloud configuration.
+[source,js]
+----
+// before
+const client = new Client({
+  cloud: {
+    id: '<cloud-id>',
+    username: 'elastic',
+    password: 'changeme'
+  }
+})
+
+// after
+const client = new Client({
+  cloud: {
+    id: '<cloud-id>'
+  },
+  auth: {
+    username: 'elastic',
+    password: 'changeme'
+  }
+})
+----
+
+If you are already passing the basic auth options in the `auth` configuration, this won't be a breaking change for you.
+
+[discrete]
+===== Calling `client.close` will reject new requests
+
+Once you call `client.close` every new request after that will be rejected with a `NoLivingConnectionsError`. In-flight requests will be executed normally unless an in-flight request requires a retry, in which case it will be rejected.
+
+[discrete]
+===== Parameters rename
+
+- `ilm.delete_lifecycle`: `policy` parameter has been renamed to `name`
+- `ilm.get_lifecycle`: `policy` parameter has been renamed to `name`
+- `ilm.put_lifecycle`: `policy` parameter has been renamed to `name`
+- `snapshot.cleanup_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.create_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.delete_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.get_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.verify_repository`: `repository` parameter has been renamed to `name`
+
+[discrete]
+===== Removal of snake_cased methods
+
+The v7 client provided snake_cased methods, such as `client.delete_by_query`. This is no longer supported, now only camelCased method are present.
+So `client.delete_by_query` can be accessed with `client.deleteByQuery`

+[[child]]
+=== Creating a child client
+
+There are some use cases where you may need multiple instances of the client. 
+You can easily do that by calling `new Client()` as many times as you need, but 
+you will lose all the benefits of using one single client, such as the long 
+living connections and the connection pool handling. To avoid this problem, the 
+client offers a `child` API, which returns a new client instance that shares the 
+connection pool with the parent client.
+
+NOTE: The event emitter is shared between the parent and the child(ren). If you 
+extend the parent client, the child client will have the same extensions, while 
+if the child client adds an extension, the parent client will not be extended.
+
+You can pass to the `child` every client option you would pass to a normal 
+client, but the connection pool specific options (`ssl`, `agent`, `pingTimeout`, 
+`Connection`, and `resurrectStrategy`).
+
+CAUTION: If you call `close` in any of the parent/child clients, every client 
+will be closed.

+providers.
+
+
+[discrete]
+[[auth-ec]]
+==== Elastic Cloud
+
+If you are using https://www.elastic.co/cloud[Elastic Cloud], the client offers
+an easy way to connect to it via the `cloud` option. You must pass the Cloud ID
+that you can find in the cloud console, then your username and password inside
+the `auth` option.
+
+NOTE: When connecting to Elastic Cloud, the client will automatically enable
+both request and response compression by default, since it yields significant
+throughput improvements. Moreover, the client will also set the tls option
+`secureProtocol` to `TLSv1_2_method` unless specified otherwise. You can still
+override this option by configuring them.
+
+IMPORTANT: Do not enable sniffing when using Elastic Cloud, since the nodes are
+behind a load balancer, Elastic Cloud will take care of everything for you.
+Take a look https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how[here]
+to know more.

+[[connect-self-managed-new]]
+=== Connecting to a self-managed cluster
+
+By default {es} will start with security features like authentication and TLS
+enabled. To connect to the {es} cluster you'll need to configure the Node.js {es}
+client to use HTTPS with the generated CA certificate in order to make requests
+successfully.
+
+If you're just getting started with {es} we recommend reading the documentation
+on https://www.elastic.co/guide/en/elasticsearch/reference/current/settings.html[configuring]
+and
+https://www.elastic.co/guide/en/elasticsearch/reference/current/starting-elasticsearch.html[starting {es}]
+to ensure your cluster is running as expected.
+
+When you start {es} for the first time you'll see a distinct block like the one
+below in the output from {es} (you may have to scroll up if it's been a while):
+
+[source,sh]
+----
+
+-> Elasticsearch security features have been automatically configured!
+-> Authentication is enabled and cluster connections are encrypted.
+
+->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):

+...
+
+----
+
+Depending on the circumstances there are two options for verifying the HTTPS
+connection, either verifying with the CA certificate itself or via the HTTP CA
+certificate fingerprint.
+
+[discrete]
+[[auth-tls]]
+==== TLS configuration
+
+The generated root CA certificate can be found in the `certs` directory in your
+{es} config location (`$ES_CONF_PATH/certs/http_ca.crt`). If you're running {es}
+in Docker there is
+https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html[additional documentation for retrieving the CA certificate].
+
+Without any additional configuration you can specify `https://` node urls, and
+the certificates used to sign these requests will be verified. To turn off
+certificate verification, you must specify an `tls` object in the top level
+config and set `rejectUnauthorized: false`. The default `tls` values are the
+same that Node.js's https://nodejs.org/api/tls.html#tls_tls_connect_options_callback[`tls.connect()`]
+uses.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://localhost:9200',
+  auth: {
+    username: 'elastic',
+    password: 'changeme'
+  },
+  tls: {
+    ca: fs.readFileSync('./http_ca.crt'),
+    rejectUnauthorized: false
+  }
+})
+----
+
+[discrete]
+[[auth-ca-fingerprint]]
+==== CA fingerprint
+
+You can configure the client to only trust certificates that are signed by a specific CA certificate
+(CA certificate pinning) by providing a `caFingerprint` option.
+This will verify that the fingerprint of the CA certificate that has signed
+the certificate of the server matches the supplied value.
+You must configure a SHA256 digest.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://example.com'
+  auth: { ... },
+  // the fingerprint (SHA256) of the CA certificate that is used to sign
+  // the certificate that the Elasticsearch node presents for TLS.
+  caFingerprint: '20:0D:CA:FA:76:...',
+  tls: {
+    // might be required if it's a self-signed certificate
+    rejectUnauthorized: false
+  }
+})
+----
+
+The certificate fingerprint can be calculated using `openssl x509` with the
+certificate file:
+
+[source,sh]
+----
+openssl x509 -fingerprint -sha256 -noout -in /path/to/http_ca.crt
+----
+
+If you don't have access to the generated CA file from {es} you can use the
+following script to output the root CA fingerprint of the {es} instance with
+`openssl s_client`:
+
+[source,sh]
+----
+# Replace the values of 'localhost' and '9200' to the
+# corresponding host and port values for the cluster.
+openssl s_client -connect localhost:9200 -servername localhost -showcerts </dev/null 2>/dev/null \
+  | openssl x509 -fingerprint -sha256 -noout -in /dev/stdin
+----
+
+The output of `openssl x509` will look something like this:
+
+[source,sh]
+----
+SHA256 Fingerprint=A5:2D:D9:35:11:E8:C6:04:5E:21:F1:66:54:B7:7C:9E:E0:F3:4A:EA:26:D9:F4:03:20:B5:31:C4:74:67:62:28

+[[auth-apikey]]
+==== ApiKey authentication
+
+You can use the
+{ref-7x}/security-api-create-api-key.html[ApiKey]
+authentication by passing the `apiKey` parameter via the `auth` option. The
+`apiKey` parameter can be either a base64 encoded string or an object with the
+values that you can obtain from the
+{ref-7x}/security-api-create-api-key.html[create api key endpoint].
+
+NOTE: If you provide both basic authentication credentials and the ApiKey
+configuration, the ApiKey takes precedence.

+    }
+  }
+})
+----
+
+[discrete]
+[[auth-bearer]]
+==== Bearer authentication
+
+You can provide your credentials by passing the `bearer` token
+parameter via the `auth` option.
+Useful for https://www.elastic.co/guide/en/elasticsearch/reference/current/security-api-create-service-token.html[service account tokens].
+Be aware that it does not handle automatic token refresh.

+})
+----
+
+
+[discrete]
+[[auth-basic]]
+==== Basic authentication
+
+You can provide your credentials by passing the `username` and `password`
+parameters via the `auth` option.
+
+NOTE: If you provide both basic authentication credentials and the Api Key
+configuration, the Api Key will take precedence.
+
+[source,js]

+----
+
+The returned value of every API call is the response body from {es}.
+If you need to access additonal metadata, such as the status code or headers,
+you must specify `meta: true` in the request options:
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' }
+})
+
+const result = await client.search({
+  index: 'my-index',
+  query: {
+    match: { hello: 'world' }
+  }
+}, { meta: true })
+----
+
+In this case, the result will be:
+[source,ts]
+----
+{
+  body: object | boolean
+  statusCode: number
+  headers: object
+  warnings: string[],
+  meta: object
+}
+----
+
+NOTE: The body is a boolean value when you use `HEAD` APIs.
+
+[discrete]
+==== Aborting a request
+
+If needed, you can abort a running request by using the `AbortController` standard.
+
+CAUTION: If you abort a request, the request will fail with a
+`RequestAbortedError`.
+
+
+[source,js]
+----
+const AbortController = require('node-abort-controller')
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' }
+})
+
+const abortController = new AbortController()
+setImmediate(() => abortController.abort())
+
+const result = await client.search({
+  index: 'my-index',
+  query: {
+    match: { hello: 'world' }
+  }
+}, { signal: abortController.signal })
+----
+
+[discrete]
+==== Request specific options
+
+If needed you can pass request specific options in a second object:
+
+[source,js]
+----
+const result = await client.search({
+  index: 'my-index',
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
+}, {
+  ignore: [404],
+  maxRetries: 3
+})
+----
+
+
+The supported request specific options are:

+=== Using the Client in a Function-as-a-Service Environment
+
+This section illustrates the best practices for leveraging the {es} client in a Function-as-a-Service (FaaS) environment.
+The most influential optimization is to initialize the client outside of the function, the global scope.
+This practice does not only improve performance but also enables background functionality as – for example – https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how[sniffing].
+The following examples provide a skeleton for the best practices.

+[[client-connect-proxy]]
+=== Connecting through a proxy
+
+~Added~ ~in~ ~`v7.10.0`~
+
+If you need to pass through an http(s) proxy for connecting to {es}, the client
+out of the box offers a handy configuration for helping you with it. Under the
+hood, it uses the https://github.com/delvedor/hpagent[`hpagent`] module.
+
+IMPORTANT: In versions 8.0+ of the client, the default `Connection` type is set to `UndiciConnection`, which does not support proxy configurations.
+To use a proxy, you will need to use the `HttpConnection` class from `@elastic/transport` instead.
+
+[source,js]
+----
+import { HttpConnection } from '@elastic/transport'
+
+const client = new Client({
+  node: 'http://localhost:9200',
+  proxy: 'http://localhost:8080',
+  Connection: HttpConnection,
+})
+----
+
+Basic authentication is supported as well:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200',
+  proxy: 'http:user:pwd@//localhost:8080',
+  Connection: HttpConnection,
+})
+----
+
+If you are connecting through a non-http(s) proxy, such as a `socks5` or `pac`,
+you can use the `agent` option to configure it.
+
+[source,js]
+----
+const SocksProxyAgent = require('socks-proxy-agent')
+const client = new Client({
+  node: 'http://localhost:9200',
+  agent () {
+    return new SocksProxyAgent('socks://127.0.0.1:1080')
+  },
+  Connection: HttpConnection,
+})
+----
+
+
+[discrete]
+[[client-error-handling]]
+=== Error handling
+
+The client exposes a variety of error objects that you can use to enhance your
+error handling. You can find all the error objects inside the `errors` key in
+the client.
+
+[source,js]
+----
+const { errors } = require('@elastic/elasticsearch')
+console.log(errors)
+----
+
+
+You can find the errors exported by the client in the table below.
+
+[cols=3*]
+|===
+|*Error*
+|*Description*
+|*Properties*
+
+|`ElasticsearchClientError`
+|Every error inherits from this class, it is the basic error generated by the client.
+a|* `name` - `string`
+* `message` - `string`
+
+|`TimeoutError`
+|Generated when a request exceeds the `requestTimeout` option.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`ConnectionError`
+|Generated when an error occurs during the request, it can be a connection error or a malformed stream of data.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`RequestAbortedError`
+|Generated if the user calls the `request.abort()` method.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`NoLivingConnectionsError`
+|Given the configuration, the ConnectionPool was not able to find a usable Connection for this request.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`SerializationError`
+|Generated if the serialization fails.
+a|* `name` - `string`
+* `message` - `string`
+* `data` - `object`, the object to serialize
+
+|`DeserializationError`
+|Generated if the deserialization fails.
+a|* `name` - `string`
+* `message` - `string`
+* `data` - `string`, the string to deserialize
+
+|`ConfigurationError`
+|Generated if there is a malformed configuration or parameter.
+a|* `name` - `string`
+* `message` - `string`
+
+|`ResponseError`
+|Generated when in case of a `4xx` or `5xx` response.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+* `body` - `object`, the response body
+* `statusCode` - `object`, the response headers
+* `headers` - `object`, the response status code
+|===
+
+[[keep-alive]]
+[discrete]
+=== Keep-alive connections
+
+By default, the client uses persistent, keep-alive connections to reduce the overhead of creating a new HTTP connection for each Elasticsearch request.
+If you are using the default `UndiciConnection` connection class, it maintains a pool of 256 connections with a keep-alive of 10 minutes.
+If you are using the legacy `HttpConnection` connection class, it maintains a pool of 256 connections with a keep-alive of 1 minute.
+
+If you need to disable keep-alive connections, you can override the HTTP agent with your preferred https://nodejs.org/api/http.html#http_new_agent_options[HTTP agent options]:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200',
+  // the function takes as parameter the option
+  // object passed to the Connection constructor
+  agent: (opts) => new CustomAgent()
+})
+----
+
+Or you can disable the HTTP agent entirely:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200',
+  // Disable agent and keep-alive
+  agent: false
+})
+----
+
+[discrete]
+[[close-connections]]
+=== Closing a client's connections
+
+If you would like to close all open connections being managed by an instance of the client, use the `close()` function:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200'
+});
+client.close();
+----
+
+[discrete]
+[[product-check]]
+=== Automatic product check
+
+Since v7.14.0, the client performs a required product check before the first call.
+This pre-flight product check allows the client to establish the version of Elasticsearch
+that it is communicating with. The product check requires one additional HTTP request to
+be sent to the server as part of the request pipeline before the main API call is sent.
+In most cases, this will succeed during the very first API call that the client sends.
+Once the product check completes, no further product check HTTP requests are sent for
+subsequent API calls.

+== Getting started
+
+This page guides you through the installation process of the Node.js client,
+shows you how to instantiate the client, and how to perform basic Elasticsearch 
+operations with it.
+
+[discrete]
+=== Requirements
+
+* https://nodejs.org/[Node.js] version 14.x or newer
+* https://docs.npmjs.com/downloading-and-installing-node-js-and-npm[`npm`], usually bundled with Node.js
+
+[discrete]
+=== Installation 
+
+To install the latest version of the client, run the following command:
+
+[source,shell]
+--------------------------
+npm install @elastic/elasticsearch
+--------------------------
+
+Refer to the <<installation>> page to learn more.
+
+
+[discrete]
+=== Connecting
+
+You can connect to the Elastic Cloud using an API key and the Elasticsearch 
+endpoint. 
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://...', // Elasticsearch endpoint
+  auth: {
+    apiKey: { // API key ID and secret
+      id: 'foo',
+      api_key: 'bar',

+You can generate an API key on the **Management** page under Security.
+
+image::images/create-api-key.png[alt="Create API key",align="center"]
+
+For other connection options, refer to the <<client-connecting>> section.
+
+
+[discrete]
+=== Operations
+
+Time to use Elasticsearch! This section walks you through the basic, and most 
+important, operations of Elasticsearch.
+
+
+[discrete]
+==== Creating an index
+
+This is how you create the `my_index` index:
+
+[source,js]
+----
+await client.indices.create({ index: 'my_index' })
+----
+
+
+[discrete]
+==== Indexing documents
+
+This is a simple way of indexing a document:
+
+[source,js]
+----
+await client.index({
+  index: 'my_index',
+  id: 'my_document_id',
+  document: {
+    foo: 'foo',
+    bar: 'bar',
+  },
+})
+----
+
+
+[discrete]
+==== Getting documents
+
+You can get documents by using the following code:
+
+[source,js]
+----
+await client.get({
+  index: 'my_index',
+  id: 'my_document_id',
+})
+----
+
+
+[discrete]
+==== Searching documents
+
+This is how you can create a single match query with the client: 
+
+[source,js]
+----
+await client.search({
+  query: {
+    match: {
+      foo: 'foo'
+    }
+  }
+})
+----
+
+
+[discrete]
+==== Updating documents
+
+This is how you can update a document, for example to add a new field:
+
+[source,js]
+----
+await client.update({
+  index: 'my_index',
+  id: 'my_document_id',
+  doc: {
+    foo: 'bar',
+    new_field: 'new value'
+  }
+})
+----
+
+
+[discrete]
+==== Deleting documents
+
+[source,js]
+----
+await client.delete({
+  index: 'my_index',
+  id: 'my_document_id',
+})
+----
+
+
+[discrete]
+==== Deleting an index
+
+[source,js]
+----
+await client.indices.delete({ index: 'my_index' })
+----
+
+
+[discrete]
+== Further reading
+
+* Use <<client-helpers>> for a more comfortable experience with the APIs.
+* For an elaborate example of how to ingest data into Elastic Cloud,

+
+CAUTION: The client helpers are experimental, and the API may change in the next
+minor releases. The helpers will not work in any Node.js version lower than 10.

+=== Bulk helper
+
+~Added~ ~in~ ~`v7.7.0`~

+// }
+----
+
+To create a new instance of the Bulk helper, access it as shown in the example
+above, the configuration options are:
+[cols=2*]
+|===
+|`datasource`
+a|An array, async generator or a readable stream with the data you need to index/create/update/delete.
+It can be an array of strings or objects, but also a stream of json strings or JavaScript objects. +
+If it is a stream, we recommend to use the https://www.npmjs.com/package/split2[`split2`] package, that splits the stream on new lines delimiters. +
+This parameter is mandatory.
+[source,js]
+----
+const { createReadStream } = require('fs')
+const split = require('split2')
+const b = client.helpers.bulk({
+  // if you just use split(), the data will be used as array of strings
+  datasource: createReadStream('./dataset.ndjson').pipe(split())
+  // if you need to manipulate the data, you can pass JSON.parse to split
+  datasource: createReadStream('./dataset.ndjson').pipe(split(JSON.parse))
+})
+----
+
+|`onDocument`
+a|A function that is called for each document of the datasource. Inside this function you can manipulate the document and you must return the operation you want to execute with the document. Look at the link:{ref}/docs-bulk.html[Bulk API documentation] to see the supported operations. +
+This parameter is mandatory.
+[source,js]
+----

+    return {
+      index: { _index: 'my-index' }
+    }
+  }

+----
+
+|`onDrop`
+a|A function that is called for everytime a document can't be indexed and it has reached the maximum amount of retries.
+[source,js]
+----
+const b = client.helpers.bulk({
+  onDrop (doc) {
+    console.log(doc)
+  }
+})
+----
+
+|`onSuccess`
+a|A function that is called for each successful operation in the bulk request, which includes the result from Elasticsearch along with the original document that was sent, or `null` for delete operations.
+[source,js]
+----
+const b = client.helpers.bulk({
+  onSuccess ({ result, document }) {
+    console.log(`SUCCESS: Document ${result.index._id} indexed to ${result.index._index}`)
+  }
+})
+----
+
+|`flushBytes`
+a|The size of the bulk body in bytes to reach before to send it. Default of 5MB. +
+_Default:_ `5000000`
+[source,js]
+----
+const b = client.helpers.bulk({
+  flushBytes: 1000000
+})
+----
+
+|`flushInterval`
+a|How much time (in milliseconds) the helper waits before flushing the body from the last document read. +
+_Default:_ `30000`
+[source,js]
+----
+const b = client.helpers.bulk({
+  flushInterval: 30000

+a|How many request is executed at the same time. +
+_Default:_ `5`
+[source,js]
+----
+const b = client.helpers.bulk({
+  concurrency: 10
+})
+----
+
+|`retries`
+a|How many times a document is retried before to call the `onDrop` callback. +
+_Default:_ Client max retries.
+[source,js]
+----
+const b = client.helpers.bulk({
+  retries: 3
+})
+----
+
+|`wait`
+a|How much time to wait before retries in milliseconds. +
+_Default:_ 5000.
+[source,js]
+----
+const b = client.helpers.bulk({
+  wait: 3000
+})
+----
+
+|`refreshOnCompletion`
+a|If `true`, at the end of the bulk operation it runs a refresh on all indices or on the specified indices. +
+_Default:_ false.
+[source,js]

+==== Modifying a document before operation
+
+~Added~ ~in~ ~`v8.8.2`~
+
+If you need to modify documents in your datasource before it is sent to Elasticsearch, you can return an array in the `onDocument` function rather than an operation object. The first item in the array must be the operation object, and the second item must be the document or partial document object as you'd like it to be sent to Elasticsearch.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')

+[discrete]
+[[multi-search-helper]]
+=== Multi search helper
+
+~Added~ ~in~ ~`v7.8.0`~
+
+If you send search request at a high rate, this helper might be useful
+for you. It uses the multi search API under the hood to batch the requests
+and improve the overall performances of your application. The `result` exposes a
+`documents` property as well, which allows you to access directly the hits
+sources.
+
+
+[discrete]
+==== Usage
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' }
+})
+const m = client.helpers.msearch()
+
+m.search(
+    { index: 'stackoverflow' },
+    { query: { match: { title: 'javascript' } } }
+  )
+  .then(result => console.log(result.body)) // or result.documents
+  .catch(err => console.error(err))
+----
+
+To create a new instance of the multi search (msearch) helper, you should access
+it as shown in the example above, the configuration options are:
+[cols=2*]
+|===
+|`operations`
+a|How many search operations should be sent in a single msearch request. +
+_Default:_ `5`
+[source,js]
+----
+const m = client.helpers.msearch({
+  operations: 10
+})
+----
+
+|`flushInterval`
+a|How much time (in milliseconds) the helper waits before flushing the operations from the last operation read. +
+_Default:_ `500`
+[source,js]
+----
+const m = client.helpers.msearch({
+  flushInterval: 500
+})
+----
+
+|`concurrency`
+a|How many request is executed at the same time. +
+_Default:_ `5`
+[source,js]
+----
+const m = client.helpers.msearch({
+  concurrency: 10
+})
+----
+
+|`retries`
+a|How many times an operation is retried before to resolve the request. An operation is retried only in case of a 429 error. +
+_Default:_ Client max retries.
+[source,js]
+----
+const m = client.helpers.msearch({
+  retries: 3
+})
+----
+
+|`wait`
+a|How much time to wait before retries in milliseconds. +
+_Default:_ 5000.
+[source,js]
+----
+const m = client.helpers.msearch({
+  wait: 3000
+})
+----
+
+|===
+
+
+[discrete]
+==== Stopping the msearch helper
+
+If needed, you can stop an msearch processor at any time. The msearch helper
+returns a https://promisesaplus.com/[thenable], which has an `stop` method.
+
+If you are creating multiple msearch helpers instances and using them for a
+limitied period of time, remember to always use the `stop` method once you have
+finished using them, otherwise your application will start leaking memory.
+
+The `stop` method accepts an optional error, that will be dispatched every
+subsequent search request.
+
+NOTE: The stop method stops the execution of the msearch processor, but if
+you are using a concurrency higher than one, the operations that are already
+running will not be stopped.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+
+const client = new Client({
+  cloud: { id: '<cloud-id>' },

+[discrete]
+[[search-helper]]
+=== Search helper
+
+~Added~ ~in~ ~`v7.7.0`~
+
+A simple wrapper around the search API. Instead of returning the entire `result`
+object it returns only the search documents source. For improving the
+performances, this helper automatically adds `filter_path=hits.hits._source` to
+the query string.
+
+[source,js]
+----
+const documents = await client.helpers.search({
+  index: 'stackoverflow',
+  query: {
+    match: {
+      title: 'javascript'
+    }
+  }
+})
+
+for (const doc of documents) {
+  console.log(doc)
+}
+----
+
+
+[discrete]
+[[scroll-search-helper]]
+=== Scroll search helper
+
+~Added~ ~in~ ~`v7.7.0`~
+
+This helpers offers a simple and intuitive way to use the scroll search API.
+Once called, it returns an
+https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function[async iterator]
+which can be used in conjuction with a for-await...of. It handles automatically
+the `429` error and uses the `maxRetries` option of the client.
+
+[source,js]
+----
+const scrollSearch = client.helpers.scrollSearch({
+  index: 'stackoverflow',
+  query: {
+    match: {
+      title: 'javascript'
+    }
+  }
+})
+
+for await (const result of scrollSearch) {
+  console.log(result)
+}
+----
+
+
+[discrete]
+==== Clear a scroll search
+
+If needed, you can clear a scroll search by calling `result.clear()`:
+
+[source,js]
+----
+for await (const result of scrollSearch) {
+  if (condition) {
+    await result.clear()
+  }
+}
+----
+
+
+[discrete]
+==== Quickly getting the documents
+
+If you only need the documents from the result of a scroll search, you can
+access them via `result.documents`:
+
+[source,js]
+----
+for await (const result of scrollSearch) {
+  console.log(result.documents)
+}
+----
+
+
+[discrete]
+[[scroll-documents-helper]]
+=== Scroll documents helper
+
+~Added~ ~in~ ~`v7.7.0`~
+
+It works in the same way as the scroll search helper, but it returns only the
+documents instead. Note, every loop cycle returns a single document, and you
+can't use the `clear` method. For improving the performances, this helper
+automatically adds `filter_path=hits.hits._source` to the query string.
+
+[source,js]
+----
+const scrollSearch = client.helpers.scrollDocuments({
+  index: 'stackoverflow',
+  query: {
+    match: {
+      title: 'javascript'
+    }
+  }
+})
+
+for await (const doc of scrollSearch) {
+  console.log(doc)
+}
+----
+
+[discrete]
+[[esql-helper]]
+=== ES|QL helper
+
+ES|QL queries can return their results in {ref}/esql-rest.html#esql-rest-format[several formats].
+The default JSON format returned by ES|QL queries contains arrays of values
+for each row, with column names and types returned separately:
+
+[discrete]
+==== Usage
+
+[discrete]
+===== `toRecords`
+
+~Added~ ~in~ ~`v8.14.0`~
+
+The default JSON format returned by ES|QL queries contains arrays of values
+for each row, with column names and types returned separately:
+
+[source,json]
+----
+{
+  "columns": [
+    { "name": "@timestamp", "type": "date" },
+    { "name": "client_ip", "type": "ip" },
+    { "name": "event_duration", "type": "long" },
+    { "name": "message", "type": "keyword" }
+  ],
+  "values": [
+    [
+      "2023-10-23T12:15:03.360Z",
+      "172.21.2.162",
+      3450233,
+      "Connected to 10.1.0.3"
+    ],
+    [
+      "2023-10-23T12:27:28.948Z",
+      "172.21.2.113",
+      2764889,
+      "Connected to 10.1.0.2"
+    ]
+  ]
+}
+----
+
+In many cases, it's preferable to operate on an array of objects, one object per row,
+rather than an array of arrays. The ES|QL `toRecords` helper converts row data into objects.
+
+[source,js]
+----
+await client.helpers
+  .esql({ query: 'FROM sample_data | LIMIT 2' })
+  .toRecords()
+// =>
+// {
+//   "columns": [
+//     { "name": "@timestamp", "type": "date" },
+//     { "name": "client_ip", "type": "ip" },
+//     { "name": "event_duration", "type": "long" },
+//     { "name": "message", "type": "keyword" }
+//   ],
+//   "records": [
+//     {
+//       "@timestamp": "2023-10-23T12:15:03.360Z",
+//       "client_ip": "172.21.2.162",
+//       "event_duration": 3450233,
+//       "message": "Connected to 10.1.0.3"
+//     },
+//     {
+//       "@timestamp": "2023-10-23T12:27:28.948Z",
+//       "client_ip": "172.21.2.113",
+//       "event_duration": 2764889,
+//       "message": "Connected to 10.1.0.2"
+//     },
+//   ]
+// }
+----
+
+In TypeScript, you can declare the type that `toRecords` returns:
+
+[source,ts]
+----
+type EventLog = {
+  '@timestamp': string,
+  client_ip: string,
+  event_duration: number,
+  message: string,
+}
+
+const result = await client.helpers
+  .esql({ query: 'FROM sample_data | LIMIT 2' })
+  .toRecords<EventLog>()
+----
+
+[discrete]
+===== `toArrowReader`
+
+~Added~ ~in~ ~`v8.16.0`~
+
+ES|QL can return results in multiple binary formats, including https://arrow.apache.org/[Apache Arrow]'s streaming format. Because it is a very efficient format to read, it can be valuable for performing high-performance in-memory analytics. And, because the response is streamed as batches of records, it can be used to produce aggregations and other calculations on larger-than-memory data sets.
+
+`toArrowReader` returns a https://arrow.apache.org/docs/js/classes/Arrow_dom.RecordBatchReader.html[`RecordBatchStreamReader`].
+
+[source,ts]
+----
+const reader = await client.helpers
+  .esql({ query: 'FROM sample_data' })
+  .toArrowReader()
+
+// print each record as JSON
+for (const recordBatch of reader) {
+  for (const record of recordBatch) {
+    console.log(record.toJSON())
+  }
+}
+----
+
+[discrete]
+===== `toArrowTable`
+
+~Added~ ~in~ ~`v8.16.0`~
+
+If you would like to pull the entire data set in Arrow format but without streaming, you can use the `toArrowTable` helper to get a https://arrow.apache.org/docs/js/classes/Arrow_dom.Table.html[Table] back instead.
+
+[source,ts]
+----
+const table = await client.helpers
+  .esql({ query: 'FROM sample_data' })
+  .toArrowTable()
+
+console.log(table.toArray())

+== Installation
+
+This page guides you through the installation process of the client.
+
+To install the latest version of the client, run the following command:

+----
+npm install @elastic/elasticsearch

+
+To install a specific major version of the client, run the following command:
+

+To learn more about the supported major versions, please refer to the
+<<js-compatibility-matrix>>.
+
+[discrete]
+[[nodejs-support]]
+=== Node.js support
+
+NOTE: The minimum supported version of Node.js is `v18`.
+
+The client versioning follows the {stack} versioning, this means that
+major, minor, and patch releases are done following a precise schedule that
+often does not coincide with the https://nodejs.org/en/about/releases/[Node.js release] times.
+
+To avoid support insecure and unsupported versions of Node.js, the
+client *will drop the support of EOL versions of Node.js between minor releases*.
+Typically, as soon as a Node.js version goes into EOL, the client will continue
+to support that version for at least another minor release. If you are using the client
+with a version of Node.js that will be unsupported soon, you will see a warning
+in your logs (the client will start logging the warning with two minors in advance).
+
+Unless you are *always* using a supported version of Node.js,
+we recommend defining the client dependency in your
+`package.json` with the `~` instead of `^`. In this way, you will lock the
+dependency on the minor release and not the major. (for example, `~7.10.0` instead
+of `^7.10.0`).

+example, a 8.12 client version won't automatically support the new features of

-# Observability [observability]
+[[observability]]
+=== Observability
 
 To observe and measure Elasticsearch client usage, several client features are provided.
 
 First, as of 8.15.0, the client provides native support for OpenTelemetry, which allows you to send client usage data to any endpoint that supports OpenTelemetry without having to make any changes to your JavaScript codebase.
 
-Also, rather than providing a default logger, the client offers an event emitter interface to hook into internal events, such as `request` and `response`, allowing you to log the events you care about, or otherwise react to client usage however you might need.

-# Creating a child client [child]
-
-There are some use cases where you may need multiple instances of the client. You can easily do that by calling `new Client()` as many times as you need, but you will lose all the benefits of using one single client, such as the long living connections and the connection pool handling. To avoid this problem, the client offers a `child` API, which returns a new client instance that shares the connection pool with the parent client.
-
-::::{note}
-The event emitter is shared between the parent and the child(ren). If you extend the parent client, the child client will have the same extensions, while if the child client adds an extension, the parent client will not be extended.
-::::
-
-
-You can pass to the `child` every client option you would pass to a normal client, but the connection pool specific options (`ssl`, `agent`, `pingTimeout`, `Connection`, and `resurrectStrategy`).
-
-::::{warning}
-If you call `close` in any of the parent/child clients, every client will be closed.

-# Client helpers [client-helpers]
-
-The client comes with an handy collection of helpers to give you a more comfortable experience with some APIs.
-
-::::{warning}
-The client helpers are experimental, and the API may change in the next minor releases. The helpers will not work in any Node.js version lower than 10.
-::::
-
-
-
-## Bulk helper [bulk-helper]
-
-Added in `v7.7.0`
-
-Running bulk requests can be complex due to the shape of the API, this helper aims to provide a nicer developer experience around the Bulk API.
-
-
-### Usage [_usage_3]
-
-```js
-const { createReadStream } = require('fs')
-const split = require('split2')
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-const result = await client.helpers.bulk({
-  datasource: createReadStream('./dataset.ndjson').pipe(split()),
-  onDocument (doc) {
-    return {
-      index: { _index: 'my-index' }
-    }
-  }
-})
-
-console.log(result)
-// {
-//   total: number,
-//   failed: number,
-//   retry: number,
-//   successful: number,
-//   time: number,
-//   bytes: number,
-//   aborted: boolean
-// }
-```
-
-To create a new instance of the Bulk helper, access it as shown in the example above, the configuration options are:
-
-|     |     |
-| --- | --- |
-| `datasource` | An array, async generator or a readable stream with the data you need to index/create/update/delete. It can be an array of strings or objects, but also a stream of json strings or JavaScript objects.<br> If it is a stream, we recommend to use the [`split2`](https://www.npmjs.com/package/split2) package, that splits the stream on new lines delimiters.<br> This parameter is mandatory.<br><br>```js<br>const { createReadStream } = require('fs')<br>const split = require('split2')<br>const b = client.helpers.bulk({<br>  // if you just use split(), the data will be used as array of strings<br>  datasource: createReadStream('./dataset.ndjson').pipe(split())<br>  // if you need to manipulate the data, you can pass JSON.parse to split<br>  datasource: createReadStream('./dataset.ndjson').pipe(split(JSON.parse))<br>})<br>```<br> |
-| `onDocument` | A function that is called for each document of the datasource. Inside this function you can manipulate the document and you must return the operation you want to execute with the document. Look at the [Bulk API documentation](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-bulk) to see the supported operations.<br> This parameter is mandatory.<br><br>```js<br>const b = client.helpers.bulk({<br>  onDocument (doc) {<br>    return {<br>      index: { _index: 'my-index' }<br>    }<br>  }<br>})<br>```<br> |
-| `onDrop` | A function that is called for everytime a document can’t be indexed and it has reached the maximum amount of retries.<br><br>```js<br>const b = client.helpers.bulk({<br>  onDrop (doc) {<br>    console.log(doc)<br>  }<br>})<br>```<br> |
-| `onSuccess` | A function that is called for each successful operation in the bulk request, which includes the result from Elasticsearch along with the original document that was sent, or `null` for delete operations.<br><br>```js<br>const b = client.helpers.bulk({<br>  onSuccess ({ result, document }) {<br>    console.log(`SUCCESS: Document ${result.index._id} indexed to ${result.index._index}`)<br>  }<br>})<br>```<br> |
-| `flushBytes` | The size of the bulk body in bytes to reach before to send it. Default of 5MB.<br> *Default:* `5000000`<br><br>```js<br>const b = client.helpers.bulk({<br>  flushBytes: 1000000<br>})<br>```<br> |
-| `flushInterval` | How much time (in milliseconds) the helper waits before flushing the body from the last document read.<br> *Default:* `30000`<br><br>```js<br>const b = client.helpers.bulk({<br>  flushInterval: 30000<br>})<br>```<br> |
-| `concurrency` | How many request is executed at the same time.<br> *Default:* `5`<br><br>```js<br>const b = client.helpers.bulk({<br>  concurrency: 10<br>})<br>```<br> |
-| `retries` | How many times a document is retried before to call the `onDrop` callback.<br> *Default:* Client max retries.<br><br>```js<br>const b = client.helpers.bulk({<br>  retries: 3<br>})<br>```<br> |
-| `wait` | How much time to wait before retries in milliseconds.<br> *Default:* 5000.<br><br>```js<br>const b = client.helpers.bulk({<br>  wait: 3000<br>})<br>```<br> |
-| `refreshOnCompletion` | If `true`, at the end of the bulk operation it runs a refresh on all indices or on the specified indices.<br> *Default:* false.<br><br>```js<br>const b = client.helpers.bulk({<br>  refreshOnCompletion: true<br>  // or<br>  refreshOnCompletion: 'index-name'<br>})<br>```<br> |

-### Supported operations [_supported_operations]
-
-
-#### Index [_index_2]
-
-```js
-client.helpers.bulk({
-  datasource: myDatasource,
-  onDocument (doc) {
-    return {
-      index: { _index: 'my-index' }
-    }
-  }
-})
-```
-
-
-#### Create [_create_4]
-
-```js
-client.helpers.bulk({
-  datasource: myDatasource,
-  onDocument (doc) {
-    return {
-      create: { _index: 'my-index', _id: doc.id }
-    }
-  }
-})
-```
-
-
-#### Update [_update_3]
-
-```js
-client.helpers.bulk({
-  datasource: myDatasource,
-  onDocument (doc) {
-    // Note that the update operation requires you to return
-    // an array, where the first element is the action, while
-    // the second are the document option
-    return [
-      { update: { _index: 'my-index', _id: doc.id } },
-      { doc_as_upsert: true }
-    ]
-  }
-})
-```
-
-
-#### Delete [_delete_10]
-
-```js
-client.helpers.bulk({
-  datasource: myDatasource,
-  onDocument (doc) {
-    return {
-      delete: { _index: 'my-index', _id: doc.id }
-    }
-  }
-})
-```
-
-
-### Abort a bulk operation [_abort_a_bulk_operation]
-
-If needed, you can abort a bulk operation at any time. The bulk helper returns a [thenable](https://promisesaplus.com/), which has an `abort` method.
-
-::::{note}
-The abort method stops the execution of the bulk operation, but if you are using a concurrency higher than one, the operations that are already running will not be stopped.
-::::
-
-
-```js
-const { createReadStream } = require('fs')
-const split = require('split2')
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-const b = client.helpers.bulk({
-  datasource: createReadStream('./dataset.ndjson').pipe(split()),
-  onDocument (doc) {
-    return {
-      index: { _index: 'my-index' }
-    }
-  },
-  onDrop (doc) {
-    b.abort()
-  }
-})
-
-console.log(await b)
-```
-
-
-### Passing custom options to the Bulk API [_passing_custom_options_to_the_bulk_api]
-
-You can pass any option supported by the link: [Bulk API](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-bulk) to the helper, and the helper uses those options in conjunction with the Bulk API call.
-
-```js
-const result = await client.helpers.bulk({
-  datasource: [...],
-  onDocument (doc) {
-    return {
-      index: { _index: 'my-index' }
-    }
-  },
-  pipeline: 'my-pipeline'
-})
-```
-
-
-### Usage with an async generator [_usage_with_an_async_generator]
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-
-async function * generator () {
-  const dataset = [
-    { user: 'jon', age: 23 },
-    { user: 'arya', age: 18 },
-    { user: 'tyrion', age: 39 }
-  ]
-  for (const doc of dataset) {
-    yield doc
-  }
-}
-
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-const result = await client.helpers.bulk({
-  datasource: generator(),
-  onDocument (doc) {
-    return {
-      index: { _index: 'my-index' }
-    }
-  }
-})
-
-console.log(result)
-```
-
-
-### Modifying a document before operation [_modifying_a_document_before_operation]
-
-Added in `v8.8.2`
-
-If you need to modify documents in your datasource before it is sent to Elasticsearch, you can return an array in the `onDocument` function rather than an operation object. The first item in the array must be the operation object, and the second item must be the document or partial document object as you’d like it to be sent to Elasticsearch.
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-const result = await client.helpers.bulk({
-  datasource: [...],
-  onDocument (doc) {
-    return [
-      { index: { _index: 'my-index' } },
-      { ...doc, favorite_color: 'mauve' },
-    ]
-  }
-})
-
-console.log(result)
-```
-
-
-## Multi search helper [multi-search-helper]
-
-Added in `v7.8.0`
-
-If you send search request at a high rate, this helper might be useful for you. It uses the multi search API under the hood to batch the requests and improve the overall performances of your application. The `result` exposes a `documents` property as well, which allows you to access directly the hits sources.
-
-
-### Usage [_usage_4]
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-const m = client.helpers.msearch()
-
-m.search(
-    { index: 'stackoverflow' },
-    { query: { match: { title: 'javascript' } } }
-  )
-  .then(result => console.log(result.body)) // or result.documents
-  .catch(err => console.error(err))
-```
-
-To create a new instance of the multi search (msearch) helper, you should access it as shown in the example above, the configuration options are:
-
-|     |     |
-| --- | --- |
-| `operations` | How many search operations should be sent in a single msearch request.<br> *Default:* `5`<br><br>```js<br>const m = client.helpers.msearch({<br>  operations: 10<br>})<br>```<br> |
-| `flushInterval` | How much time (in milliseconds) the helper waits before flushing the operations from the last operation read.<br> *Default:* `500`<br><br>```js<br>const m = client.helpers.msearch({<br>  flushInterval: 500<br>})<br>```<br> |
-| `concurrency` | How many request is executed at the same time.<br> *Default:* `5`<br><br>```js<br>const m = client.helpers.msearch({<br>  concurrency: 10<br>})<br>```<br> |
-| `retries` | How many times an operation is retried before to resolve the request. An operation is retried only in case of a 429 error.<br> *Default:* Client max retries.<br><br>```js<br>const m = client.helpers.msearch({<br>  retries: 3<br>})<br>```<br> |
-| `wait` | How much time to wait before retries in milliseconds.<br> *Default:* 5000.<br><br>```js<br>const m = client.helpers.msearch({<br>  wait: 3000<br>})<br>```<br> |
-
-
-### Stopping the msearch helper [_stopping_the_msearch_helper]
-
-If needed, you can stop an msearch processor at any time. The msearch helper returns a [thenable](https://promisesaplus.com/), which has an `stop` method.
-
-If you are creating multiple msearch helpers instances and using them for a limitied period of time, remember to always use the `stop` method once you have finished using them, otherwise your application will start leaking memory.
-
-The `stop` method accepts an optional error, that will be dispatched every subsequent search request.
-
-::::{note}
-The stop method stops the execution of the msearch processor, but if you are using a concurrency higher than one, the operations that are already running will not be stopped.
-::::
-
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-const m = client.helpers.msearch()
-
-m.search(
-    { index: 'stackoverflow' },
-    { query: { match: { title: 'javascript' } } }
-  )
-  .then(result => console.log(result.body))
-  .catch(err => console.error(err))
-
-m.search(
-    { index: 'stackoverflow' },
-    { query: { match: { title: 'ruby' } } }
-  )
-  .then(result => console.log(result.body))
-  .catch(err => console.error(err))
-
-setImmediate(() => m.stop())
-```
-
-
-## Search helper [search-helper]
-
-Added in `v7.7.0`
-
-A simple wrapper around the search API. Instead of returning the entire `result` object it returns only the search documents source. For improving the performances, this helper automatically adds `filter_path=hits.hits._source` to the query string.
-
-```js
-const documents = await client.helpers.search({
-  index: 'stackoverflow',
-  query: {
-    match: {
-      title: 'javascript'
-    }
-  }
-})
-
-for (const doc of documents) {
-  console.log(doc)
-}
-```
-
-
-## Scroll search helper [scroll-search-helper]
-
-Added in `v7.7.0`
-
-This helpers offers a simple and intuitive way to use the scroll search API. Once called, it returns an [async iterator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function) which can be used in conjuction with a for-await…​of. It handles automatically the `429` error and uses the `maxRetries` option of the client.
-
-```js
-const scrollSearch = client.helpers.scrollSearch({
-  index: 'stackoverflow',
-  query: {
-    match: {
-      title: 'javascript'
-    }
-  }
-})
-
-for await (const result of scrollSearch) {
-  console.log(result)
-}
-```
-
-
-### Clear a scroll search [_clear_a_scroll_search]
-
-If needed, you can clear a scroll search by calling `result.clear()`:
-
-```js
-for await (const result of scrollSearch) {
-  if (condition) {
-    await result.clear()
-  }
-}
-```
-
-
-### Quickly getting the documents [_quickly_getting_the_documents]
-
-If you only need the documents from the result of a scroll search, you can access them via `result.documents`:
-
-```js
-for await (const result of scrollSearch) {
-  console.log(result.documents)
-}
-```
-
-
-## Scroll documents helper [scroll-documents-helper]
-
-Added in `v7.7.0`
-
-It works in the same way as the scroll search helper, but it returns only the documents instead. Note, every loop cycle returns a single document, and you can’t use the `clear` method. For improving the performances, this helper automatically adds `filter_path=hits.hits._source` to the query string.
-
-```js
-const scrollSearch = client.helpers.scrollDocuments({
-  index: 'stackoverflow',
-  query: {
-    match: {
-      title: 'javascript'
-    }
-  }
-})
-
-for await (const doc of scrollSearch) {
-  console.log(doc)
-}
-```
-
-
-## ES|QL helper [esql-helper]
-
-ES|QL queries can return their results in [several formats](docs-content://explore-analyze/query-filter/languages/esql-rest.md#esql-rest-format). The default JSON format returned by ES|QL queries contains arrays of values for each row, with column names and types returned separately:
-
-
-### Usage [_usage_5]
-
-
-#### `toRecords` [_torecords]
-
-Added in `v8.14.0`
-
-The default JSON format returned by ES|QL queries contains arrays of values for each row, with column names and types returned separately:
-
-```json
-{
-  "columns": [
-    { "name": "@timestamp", "type": "date" },
-    { "name": "client_ip", "type": "ip" },
-    { "name": "event_duration", "type": "long" },
-    { "name": "message", "type": "keyword" }
-  ],
-  "values": [
-    [
-      "2023-10-23T12:15:03.360Z",
-      "172.21.2.162",
-      3450233,
-      "Connected to 10.1.0.3"
-    ],
-    [
-      "2023-10-23T12:27:28.948Z",
-      "172.21.2.113",
-      2764889,
-      "Connected to 10.1.0.2"
-    ]
-  ]
-}
-```
-
-In many cases, it’s preferable to operate on an array of objects, one object per row, rather than an array of arrays. The ES|QL `toRecords` helper converts row data into objects.
-
-```js
-await client.helpers
-  .esql({ query: 'FROM sample_data | LIMIT 2' })
-  .toRecords()
-// =>
-// {
-//   "columns": [
-//     { "name": "@timestamp", "type": "date" },
-//     { "name": "client_ip", "type": "ip" },
-//     { "name": "event_duration", "type": "long" },
-//     { "name": "message", "type": "keyword" }
-//   ],
-//   "records": [
-//     {
-//       "@timestamp": "2023-10-23T12:15:03.360Z",
-//       "client_ip": "172.21.2.162",
-//       "event_duration": 3450233,
-//       "message": "Connected to 10.1.0.3"
-//     },
-//     {
-//       "@timestamp": "2023-10-23T12:27:28.948Z",
-//       "client_ip": "172.21.2.113",
-//       "event_duration": 2764889,
-//       "message": "Connected to 10.1.0.2"
-//     },
-//   ]
-// }
-```
-
-In TypeScript, you can declare the type that `toRecords` returns:
-
-```ts
-type EventLog = {
-  '@timestamp': string,
-  client_ip: string,
-  event_duration: number,
-  message: string,
-}
-
-const result = await client.helpers
-  .esql({ query: 'FROM sample_data | LIMIT 2' })
-  .toRecords<EventLog>()
-```
-
-
-#### `toArrowReader` [_toarrowreader]
-
-Added in `v8.16.0`
-
-ES|QL can return results in multiple binary formats, including [Apache Arrow](https://arrow.apache.org/)'s streaming format. Because it is a very efficient format to read, it can be valuable for performing high-performance in-memory analytics. And, because the response is streamed as batches of records, it can be used to produce aggregations and other calculations on larger-than-memory data sets.
-
-`toArrowReader` returns a [`RecordBatchStreamReader`](https://arrow.apache.org/docs/js/classes/Arrow_dom.RecordBatchReader.md).
-
-```ts
-const reader = await client.helpers
-  .esql({ query: 'FROM sample_data' })
-  .toArrowReader()
-
-// print each record as JSON
-for (const recordBatch of reader) {
-  for (const record of recordBatch) {
-    console.log(record.toJSON())
-  }
-}
-```
-
-
-#### `toArrowTable` [_toarrowtable]
-
-Added in `v8.16.0`
-
-If you would like to pull the entire data set in Arrow format but without streaming, you can use the `toArrowTable` helper to get a [Table](https://arrow.apache.org/docs/js/classes/Arrow_dom.Table.md) back instead.
-
-```ts
-const table = await client.helpers
-  .esql({ query: 'FROM sample_data' })
-  .toArrowTable()
-
-console.log(table.toArray())
-```

-# Testing [client-testing]
-
-Testing is one of the most important parts of developing an application. The client is very flexible when it comes to testing and is compatible with most testing frameworks (such as [`ava`](https://www.npmjs.com/package/ava), which is used in the examples below).
-
-If you are using this client, you are most likely working with {{es}}, and one of the first issues you face is how to test your application. A perfectly valid solution is to use the real {{es}} instance for testing your application, but you would be doing an integration test, while you want a unit test. There are many ways to solve this problem, you could create the database with Docker, or use an in-memory compatible one, but if you are writing unit tests that can be easily parallelized this becomes quite uncomfortable. A different way of improving your testing experience while doing unit tests is to use a mock.
-
-The client is designed to be easy to extend and adapt to your needs. Thanks to its internal architecture it allows you to change some specific components while keeping the rest of it working as usual. Each {{es}} official client is composed of the following components:
-
-* `API layer`: every {{es}} API that you can call.
-* `Transport`: a component that takes care of preparing a request before sending it and handling all the retry and sniffing strategies.
-* `ConnectionPool`: {{es}} is a cluster and might have multiple nodes, the `ConnectionPool` takes care of them.
-* `Serializer`: A class with all the serialization strategies, from the basic JSON to the new line delimited JSON.
-* `Connection`: The actual HTTP library.
-
-The best way to mock {{es}} with the official clients is to replace the `Connection` component since it has very few responsibilities and it does not interact with other internal components other than getting requests and returning responses.
-
-
-## `@elastic/elasticsearch-mock` [_elasticelasticsearch_mock]
-
-Writing each time a mock for your test can be annoying and error-prone, so we have built a simple yet powerful mocking library specifically designed for this client, and you can install it with the following command:
-
-```sh
-npm install @elastic/elasticsearch-mock --save-dev
-```
-
-With this library you can create custom mocks for any request you can send to {{es}}. It offers a simple and intuitive API and it mocks only the HTTP layer, leaving the rest of the client working as usual.
-
-Before showing all of its features, and what you can do with it, let’s see an example:
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const Mock = require('@elastic/elasticsearch-mock')
-
-const mock = new Mock()
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' },
-  Connection: mock.getConnection()
-})
-
-mock.add({
-  method: 'GET',
-  path: '/'
-}, () => {
-  return { status: 'ok' }
-})
-
-client.info().then(console.log, console.log)
-```
-
-As you can see it works closely with the client itself, once you have created a new instance of the mock library you just need to call the mock.getConnection() method and pass its result to the Connection option of the client. From now on, every request is handled by the mock library,  and the HTTP layer will never be touched. As a result, your test is significantly faster and you are able to easily parallelize them!
-
-The library allows you to write both “strict” and “loose” mocks, which means that you can write a mock that handles a very specific request or be looser and handle a group of request, let’s see this in action:
-
-```js
-mock.add({
-  method: 'POST',
-  path: '/indexName/_search'
-}, () => {
-  return {
-    hits: {
-      total: { value: 1, relation: 'eq' },
-      hits: [{ _source: { baz: 'faz' } }]
-    }
-  }
-})
-
-mock.add({
-  method: 'POST',
-  path: '/indexName/_search',
-  body: { query: { match: { foo: 'bar' } } }
-}, () => {
-  return {
-    hits: {
-      total: { value: 0, relation: 'eq' },
-      hits: []
-    }
-  }
-})
-```
-
-In the example above, every search request gets the first response, while every search request that uses the query described in the second mock gets the second response.
-
-You can also specify dynamic paths:
-
-```js
-mock.add({
-  method: 'GET',
-  path: '/:index/_count'
-}, () => {
-  return { count: 42 }
-})
-
-client.count({ index: 'foo' }).then(console.log, console.log) // => { count: 42 }
-client.count({ index: 'bar' }).then(console.log, console.log) // => { count: 42 }
-```
-
-And wildcards are supported as well.
-
-Another very interesting use case is the ability to create a test that randomly fails to see how your code reacts to failures:
-
-```js
-mock.add({
-  method: 'GET',
-  path: '/:index/_count'
-}, () => {
-  if (Math.random() > 0.8) {
-    return ResponseError({ body: {}, statusCode: 500 })
-  } else {
-    return { count: 42 }
-  }
-})
-```
-
-We have seen how simple is mocking {{es}} and testing your application, you can find many more features and examples in the [module documentation](https://github.com/elastic/elasticsearch-js-mock).

-# Connecting [client-connecting]
-
-This page contains the information you need to connect and use the Client with {{es}}.
-
-## Authentication [authentication]
-
-This document contains code snippets to show you how to connect to various {{es}} providers.
-
-
-### Elastic Cloud [auth-ec]
-
-If you are using [Elastic Cloud](https://www.elastic.co/cloud), the client offers an easy way to connect to it via the `cloud` option. You must pass the Cloud ID that you can find in the cloud console, then your username and password inside the `auth` option.
-
-::::{note}
-When connecting to Elastic Cloud, the client will automatically enable both request and response compression by default, since it yields significant throughput improvements. Moreover, the client will also set the tls option `secureProtocol` to `TLSv1_2_method` unless specified otherwise. You can still override this option by configuring them.
-::::
-
-
-::::{important}
-Do not enable sniffing when using Elastic Cloud, since the nodes are behind a load balancer, Elastic Cloud will take care of everything for you. Take a look [here](https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how) to know more.
-::::
-
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  cloud: {
-    id: '<cloud-id>'
-  },
-  auth: {
-    username: 'elastic',
-    password: 'changeme'
-  }
-})
-```
-
-
-## Connecting to a self-managed cluster [connect-self-managed-new]
-
-By default {{es}} will start with security features like authentication and TLS enabled. To connect to the {{es}} cluster you’ll need to configure the Node.js {{es}} client to use HTTPS with the generated CA certificate in order to make requests successfully.
-
-If you’re just getting started with {{es}} we recommend reading the documentation on [configuring](docs-content://deploy-manage/deploy/self-managed/configure-elasticsearch.md) and [starting {{es}}](docs-content://deploy-manage/maintenance/start-stop-services/start-stop-elasticsearch.md) to ensure your cluster is running as expected.
-
-When you start {{es}} for the first time you’ll see a distinct block like the one below in the output from {{es}} (you may have to scroll up if it’s been a while):
-
-```sh
--> Elasticsearch security features have been automatically configured!
--> Authentication is enabled and cluster connections are encrypted.
-
-->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
-  lhQpLELkjkrawaBoaz0Q
-
-->  HTTP CA certificate SHA-256 fingerprint:
-  a52dd93511e8c6045e21f16654b77c9ee0f34aea26d9f40320b531c474676228
-...
-```
-
-Depending on the circumstances there are two options for verifying the HTTPS connection, either verifying with the CA certificate itself or via the HTTP CA certificate fingerprint.
-
-
-### TLS configuration [auth-tls]
-
-The generated root CA certificate can be found in the `certs` directory in your {{es}} config location (`$ES_CONF_PATH/certs/http_ca.crt`). If you’re running {{es}} in Docker there is [additional documentation for retrieving the CA certificate](docs-content://deploy-manage/deploy/self-managed/install-elasticsearch-with-docker.md).
-
-Without any additional configuration you can specify `https://` node urls, and the certificates used to sign these requests will be verified. To turn off certificate verification, you must specify an `tls` object in the top level config and set `rejectUnauthorized: false`. The default `tls` values are the same that Node.js’s [`tls.connect()`](https://nodejs.org/api/tls.md#tls_tls_connect_options_callback) uses.
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://localhost:9200',
-  auth: {
-    username: 'elastic',
-    password: 'changeme'
-  },
-  tls: {
-    ca: fs.readFileSync('./http_ca.crt'),
-    rejectUnauthorized: false
-  }
-})
-```
-
-
-### CA fingerprint [auth-ca-fingerprint]
-
-You can configure the client to only trust certificates that are signed by a specific CA certificate (CA certificate pinning) by providing a `caFingerprint` option. This will verify that the fingerprint of the CA certificate that has signed the certificate of the server matches the supplied value. You must configure a SHA256 digest.
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://example.com'
-  auth: { ... },
-  // the fingerprint (SHA256) of the CA certificate that is used to sign
-  // the certificate that the Elasticsearch node presents for TLS.
-  caFingerprint: '20:0D:CA:FA:76:...',
-  tls: {
-    // might be required if it's a self-signed certificate
-    rejectUnauthorized: false
-  }
-})
-```
-
-The certificate fingerprint can be calculated using `openssl x509` with the certificate file:
-
-```sh
-openssl x509 -fingerprint -sha256 -noout -in /path/to/http_ca.crt
-```
-
-If you don’t have access to the generated CA file from {{es}} you can use the following script to output the root CA fingerprint of the {{es}} instance with `openssl s_client`:
-
-```sh
-# Replace the values of 'localhost' and '9200' to the
-# corresponding host and port values for the cluster.
-openssl s_client -connect localhost:9200 -servername localhost -showcerts </dev/null 2>/dev/null \
-  | openssl x509 -fingerprint -sha256 -noout -in /dev/stdin
-```
-
-The output of `openssl x509` will look something like this:
-
-```sh
-SHA256 Fingerprint=A5:2D:D9:35:11:E8:C6:04:5E:21:F1:66:54:B7:7C:9E:E0:F3:4A:EA:26:D9:F4:03:20:B5:31:C4:74:67:62:28
-```
-
-
-## Connecting without security enabled [connect-no-security]
-
-::::{warning}
-Running {{es}} without security enabled is not recommended.
-::::
-
-
-If your cluster is configured with [security explicitly disabled](elasticsearch://reference/elasticsearch/configuration-reference/security-settings.md) then you can connect via HTTP:
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'http://example.com'
-})
-```
-
-
-## Authentication strategies [auth-strategies]
-
-Following you can find all the supported authentication strategies.
-
-
-### ApiKey authentication [auth-apikey]
-
-You can use the [ApiKey](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-security-create-api-key) authentication by passing the `apiKey` parameter via the `auth` option. The `apiKey` parameter can be either a base64 encoded string or an object with the values that you can obtain from the [create api key endpoint](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-security-create-api-key).
-
-::::{note}
-If you provide both basic authentication credentials and the ApiKey configuration, the ApiKey takes precedence.
-::::
-
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://localhost:9200',
-  auth: {
-    apiKey: 'base64EncodedKey'
-  }
-})
-```
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://localhost:9200',
-  auth: {
-    apiKey: {
-      id: 'foo',
-      api_key: 'bar'
-    }
-  }
-})
-```
-
-
-### Bearer authentication [auth-bearer]
-
-You can provide your credentials by passing the `bearer` token parameter via the `auth` option. Useful for [service account tokens](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-security-create-service-token). Be aware that it does not handle automatic token refresh.
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://localhost:9200',
-  auth: {
-    bearer: 'token'
-  }
-})
-```
-
-
-### Basic authentication [auth-basic]
-
-You can provide your credentials by passing the `username` and `password` parameters via the `auth` option.
-
-::::{note}
-If you provide both basic authentication credentials and the Api Key configuration, the Api Key will take precedence.
-::::
-
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://localhost:9200',
-  auth: {
-    username: 'elastic',
-    password: 'changeme'
-  }
-})
-```
-
-Otherwise, you can provide your credentials in the node(s) URL.
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://username:password@localhost:9200'
-})
-```
-
-
-## Usage [client-usage]
-
-Using the client is straightforward, it supports all the public APIs of {{es}}, and every method exposes the same signature.
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-
-const result = await client.search({
-  index: 'my-index',
-  query: {
-    match: { hello: 'world' }
-  }
-})
-```
-
-The returned value of every API call is the response body from {{es}}. If you need to access additonal metadata, such as the status code or headers, you must specify `meta: true` in the request options:
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-
-const result = await client.search({
-  index: 'my-index',
-  query: {
-    match: { hello: 'world' }
-  }
-}, { meta: true })
-```
-
-In this case, the result will be:
-
-```ts
-{
-  body: object | boolean
-  statusCode: number
-  headers: object
-  warnings: string[],
-  meta: object
-}
-```
-
-::::{note}
-The body is a boolean value when you use `HEAD` APIs.
-::::
-
-
-
-### Aborting a request [_aborting_a_request]
-
-If needed, you can abort a running request by using the `AbortController` standard.
-
-::::{warning}
-If you abort a request, the request will fail with a `RequestAbortedError`.
-::::
-
-
-```js
-const AbortController = require('node-abort-controller')
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-
-const abortController = new AbortController()
-setImmediate(() => abortController.abort())
-
-const result = await client.search({
-  index: 'my-index',
-  query: {
-    match: { hello: 'world' }
-  }
-}, { signal: abortController.signal })
-```
-
-
-### Request specific options [_request_specific_options]
-
-If needed you can pass request specific options in a second object:
-
-```js
-const result = await client.search({
-  index: 'my-index',
-  body: {
-    query: {
-      match: { hello: 'world' }
-    }
-  }
-}, {
-  ignore: [404],
-  maxRetries: 3
-})
-```
-
-The supported request specific options are:
-
-| Option | Description |
-| --- | ----------- |
-| `ignore` | `number[]` -  HTTP status codes which should not be considered errors for this request.<br>*Default:* `null` |
-| `requestTimeout` | `number` or `string` - Max request timeout for the request in milliseconds. This overrides the client default, which is to not time out at all. See [Elasticsearch best practices for HTML clients](elasticsearch://reference/elasticsearch/configuration-reference/networking-settings.md#_http_client_configuration) for more info.<br>_Default:* No timeout |
-| `retryOnTimeout` | `boolean` - Retry requests that have timed out.*Default:* `false` |
-| `maxRetries` | `number` - Max number of retries for the request, it overrides the client default.<br>*Default:* `3` |
-| `compression` | `string` or  `boolean` - Enables body compression for the request.<br>*Options:* `false`, `'gzip'`<br>*Default:* `false` |
-| `asStream` | `boolean` - Instead of getting the parsed body back, you get the raw Node.js stream of data.<br>*Default:* `false` |
-| `headers` | `object` - Custom headers for the request.<br>*Default:* `null` |
-|`querystring` | `object` - Custom querystring for the request.<br>*Default:* `null` |
-| `id` | `any` - Custom request ID. *(overrides the top level request id generator)*<br>*Default:* `null` |
-| `context` | `any` - Custom object per request. *(you can use it to pass data to the clients events)*<br>*Default:* `null` |
-| `opaqueId` | `string` - Set the `X-Opaque-Id` HTTP header. See [X-Opaque-Id HTTP header](elasticsearch://reference/elasticsearch/rest-apis/api-conventions.md#x-opaque-id) *Default:* `null` |
-| `maxResponseSize` | `number` - When configured, it verifies that the uncompressed response size is lower than the configured number, if it’s higher it will abort the request. It cannot be higher than buffer.constants.MAX_STRING_LENTGH<br>*Default:* `null` |
-| `maxCompressedResponseSize` | `number` - When configured, it verifies that the compressed response size is lower than the configured number, if it’s higher it will abort the request. It cannot be higher than buffer.constants.MAX_LENTGH<br>*Default:* `null` |
-| `signal` | `AbortSignal` - The AbortSignal instance to allow request abortion.<br>*Default:* `null` |
-| `meta` | `boolean` - Rather than returning the body, return an object containing `body`, `statusCode`, `headers` and `meta` keys<br>*Default*: `false` |
-| `redaction` | `object` - Options for redacting potentially sensitive data from error metadata. See [Redaction of potentially sensitive data](/reference/advanced-config.md#redaction). | `retryBackoff` |

-## Using the Client in a Function-as-a-Service Environment [client-faas-env]
-
-This section illustrates the best practices for leveraging the {{es}} client in a Function-as-a-Service (FaaS) environment. The most influential optimization is to initialize the client outside of the function, the global scope. This practice does not only improve performance but also enables background functionality as – for example – [sniffing](https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how). The following examples provide a skeleton for the best practices.
-
-
-### GCP Cloud Functions [_gcp_cloud_functions]
-
-```js
-'use strict'
-
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  // client initialisation
-})
-
-exports.testFunction = async function (req, res) {
-  // use the client
-}
-```
-
-
-### AWS Lambda [_aws_lambda]
-
-```js
-'use strict'
-
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  // client initialisation
-})
-
-exports.handler = async function (event, context) {
-  // use the client
-}
-```
-
-
-### Azure Functions [_azure_functions]
-
-```js
-'use strict'
-
-const { Client } = require('@elastic/elasticsearch')
-
-const client = new Client({
-  // client initialisation
-})
-
-module.exports = async function (context, req) {
-  // use the client
-}
-```
-
-Resources used to assess these recommendations:

-## Connecting through a proxy [client-connect-proxy]
-
-Added in `v7.10.0`
-
-If you need to pass through an http(s) proxy for connecting to {{es}}, the client out of the box offers a handy configuration for helping you with it. Under the hood, it uses the [`hpagent`](https://github.com/delvedor/hpagent) module.
-
-::::{important}
-In versions 8.0+ of the client, the default `Connection` type is set to `UndiciConnection`, which does not support proxy configurations. To use a proxy, you will need to use the `HttpConnection` class from `@elastic/transport` instead.
-::::
-
-
-```js
-import { HttpConnection } from '@elastic/transport'
-
-const client = new Client({
-  node: 'http://localhost:9200',
-  proxy: 'http://localhost:8080',
-  Connection: HttpConnection,
-})
-```
-
-Basic authentication is supported as well:
-
-```js
-const client = new Client({
-  node: 'http://localhost:9200',
-  proxy: 'http:user:pwd@//localhost:8080',
-  Connection: HttpConnection,
-})
-```
-
-If you are connecting through a non-http(s) proxy, such as a `socks5` or `pac`, you can use the `agent` option to configure it.
-
-```js
-const SocksProxyAgent = require('socks-proxy-agent')
-const client = new Client({
-  node: 'http://localhost:9200',
-  agent () {
-    return new SocksProxyAgent('socks://127.0.0.1:1080')
-  },
-  Connection: HttpConnection,
-})
-```
-
-
-## Error handling [client-error-handling]
-
-The client exposes a variety of error objects that you can use to enhance your error handling. You can find all the error objects inside the `errors` key in the client.
-
-```js
-const { errors } = require('@elastic/elasticsearch')
-console.log(errors)
-```
-
-You can find the errors exported by the client in the table below.
-
-|     |     |     |
-| --- | --- | --- |
-| **Error** | **Description** | **Properties** |
-| `ElasticsearchClientError` | Every error inherits from this class, it is the basic error generated by the client. | * `name` - `string`<br>* `message` - `string`<br> |
-| `TimeoutError` | Generated when a request exceeds the `requestTimeout` option. | * `name` - `string`<br>* `message` - `string`<br>* `meta` - `object`, contains all the information about the request<br> |
-| `ConnectionError` | Generated when an error occurs during the request, it can be a connection error or a malformed stream of data. | * `name` - `string`<br>* `message` - `string`<br>* `meta` - `object`, contains all the information about the request<br> |
-| `RequestAbortedError` | Generated if the user calls the `request.abort()` method. | * `name` - `string`<br>* `message` - `string`<br>* `meta` - `object`, contains all the information about the request<br> |
-| `NoLivingConnectionsError` | Given the configuration, the ConnectionPool was not able to find a usable Connection for this request. | * `name` - `string`<br>* `message` - `string`<br>* `meta` - `object`, contains all the information about the request<br> |
-| `SerializationError` | Generated if the serialization fails. | * `name` - `string`<br>* `message` - `string`<br>* `data` - `object`, the object to serialize<br> |
-| `DeserializationError` | Generated if the deserialization fails. | * `name` - `string`<br>* `message` - `string`<br>* `data` - `string`, the string to deserialize<br> |
-| `ConfigurationError` | Generated if there is a malformed configuration or parameter. | * `name` - `string`<br>* `message` - `string`<br> |
-| `ResponseError` | Generated when in case of a `4xx` or `5xx` response. | * `name` - `string`<br>* `message` - `string`<br>* `meta` - `object`, contains all the information about the request<br>* `body` - `object`, the response body<br>* `statusCode` - `object`, the response headers<br>* `headers` - `object`, the response status code<br> |
-
-
-## Keep-alive connections [keep-alive]
-
-By default, the client uses persistent, keep-alive connections to reduce the overhead of creating a new HTTP connection for each Elasticsearch request. If you are using the default `UndiciConnection` connection class, it maintains a pool of 256 connections with a keep-alive of 10 minutes. If you are using the legacy `HttpConnection` connection class, it maintains a pool of 256 connections with a keep-alive of 1 minute.
-
-If you need to disable keep-alive connections, you can override the HTTP agent with your preferred [HTTP agent options](https://nodejs.org/api/http.md#http_new_agent_options):
-
-```js
-const client = new Client({
-  node: 'http://localhost:9200',
-  // the function takes as parameter the option
-  // object passed to the Connection constructor
-  agent: (opts) => new CustomAgent()
-})
-```
-
-Or you can disable the HTTP agent entirely:
-
-```js
-const client = new Client({
-  node: 'http://localhost:9200',
-  // Disable agent and keep-alive
-  agent: false
-})
-```
-
-
-## Closing a client’s connections [close-connections]
-
-If you would like to close all open connections being managed by an instance of the client, use the `close()` function:
-
-```js
-const client = new Client({
-  node: 'http://localhost:9200'
-});
-client.close();
-```
-
-
-## Automatic product check [product-check]
-
-Since v7.14.0, the client performs a required product check before the first call. This pre-flight product check allows the client to establish the version of Elasticsearch that it is communicating with. The product check requires one additional HTTP request to be sent to the server as part of the request pipeline before the main API call is sent. In most cases, this will succeed during the very first API call that the client sends. Once the product check completes, no further product check HTTP requests are sent for subsequent API calls.

-# Getting started [getting-started-js]
-
-This page guides you through the installation process of the Node.js client, shows you how to instantiate the client, and how to perform basic Elasticsearch operations with it.
-
-
-### Requirements [_requirements]
-
-* [Node.js](https://nodejs.org/) version 14.x or newer
-* [`npm`](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm), usually bundled with Node.js
-
-
-### Installation [_installation]
-
-To install the latest version of the client, run the following command:
-
-```shell
-npm install @elastic/elasticsearch
-```
-
-Refer to the [*Installation*](/reference/installation.md) page to learn more.
-
-
-### Connecting [_connecting]
-
-You can connect to the Elastic Cloud using an API key and the Elasticsearch endpoint.
-
-```js
-const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
-  node: 'https://...', // Elasticsearch endpoint
-  auth: {
-    apiKey: { // API key ID and secret
-      id: 'foo',
-      api_key: 'bar',
-    }
-  }
-})
-```
-
-Your Elasticsearch endpoint can be found on the **My deployment** page of your deployment:
-
-:::{image} ../images/es-endpoint.jpg
-:alt: Finding Elasticsearch endpoint
-:::
-
-You can generate an API key on the **Management** page under Security.
-
-:::{image} ../images/create-api-key.png
-:alt: Create API key
-:::
-
-For other connection options, refer to the [*Connecting*](/reference/connecting.md) section.
-
-
-### Operations [_operations]
-
-Time to use Elasticsearch! This section walks you through the basic, and most important, operations of Elasticsearch.
-
-
-#### Creating an index [_creating_an_index]
-
-This is how you create the `my_index` index:
-
-```js
-await client.indices.create({ index: 'my_index' })
-```
-
-
-#### Indexing documents [_indexing_documents]
-
-This is a simple way of indexing a document:
-
-```js
-await client.index({
-  index: 'my_index',
-  id: 'my_document_id',
-  document: {
-    foo: 'foo',
-    bar: 'bar',
-  },
-})
-```
-
-
-#### Getting documents [_getting_documents]
-
-You can get documents by using the following code:
-
-```js
-await client.get({
-  index: 'my_index',
-  id: 'my_document_id',
-})
-```
-
-
-#### Searching documents [_searching_documents]
-
-This is how you can create a single match query with the client:
-
-```js
-await client.search({
-  query: {
-    match: {
-      foo: 'foo'
-    }
-  }
-})
-```
-
-
-#### Updating documents [_updating_documents]
-
-This is how you can update a document, for example to add a new field:
-
-```js
-await client.update({
-  index: 'my_index',
-  id: 'my_document_id',
-  doc: {
-    foo: 'bar',
-    new_field: 'new value'
-  }
-})
-```
-
-
-#### Deleting documents [_deleting_documents]
-
-```js
-await client.delete({
-  index: 'my_index',
-  id: 'my_document_id',
-})
-```
-
-
-#### Deleting an index [_deleting_an_index]
-
-```js
-await client.indices.delete({ index: 'my_index' })
-```
-
-
-## Further reading [_further_reading]
-
-* Use [*Client helpers*](/reference/client-helpers.md) for a more comfortable experience with the APIs.
-* For an elaborate example of how to ingest data into Elastic Cloud, refer to [this page](docs-content://manage-data/ingest/ingesting-data-from-applications/ingest-data-with-nodejs-on-elasticsearch-service.md).

-# Installation [installation]
-
-This page guides you through the installation process of the client.
-
-To install the latest version of the client, run the following command:
-
-```sh
-npm install @elastic/elasticsearch
-```
-
-To install a specific major version of the client, run the following command:
-
-```sh
-npm install @elastic/elasticsearch@<major>
-```
-
-To learn more about the supported major versions, please refer to the [Compatibility matrix](#js-compatibility-matrix).
-
-
-## Node.js support [nodejs-support]
-
-::::{note}
-The minimum supported version of Node.js is `v18`.
-::::
-
-
-The client versioning follows the {{stack}} versioning, this means that major, minor, and patch releases are done following a precise schedule that often does not coincide with the [Node.js release](https://nodejs.org/en/about/releases/) times.
-
-To avoid support insecure and unsupported versions of Node.js, the client **will drop the support of EOL versions of Node.js between minor releases**. Typically, as soon as a Node.js version goes into EOL, the client will continue to support that version for at least another minor release. If you are using the client with a version of Node.js that will be unsupported soon, you will see a warning in your logs (the client will start logging the warning with two minors in advance).
-
-Unless you are **always** using a supported version of Node.js, we recommend defining the client dependency in your `package.json` with the `~` instead of `^`. In this way, you will lock the dependency on the minor release and not the major. (for example, `~7.10.0` instead of `^7.10.0`).
-
-| Node.js Version | Node.js EOL date | End of support |
-| --- | --- | --- |
-| `8.x` | December 2019 | `7.11` (early 2021) |
-| `10.x` | April 2021 | `7.12` (mid 2021) |
-| `12.x` | April 2022 | `8.2` (early 2022) |
-| `14.x` | April 2023 | `8.8` (early 2023) |
-| `16.x` | September 2023 | `8.11` (late 2023) |
-
-
-## Compatibility matrix [js-compatibility-matrix]
-
-Language clients are forward compatible; meaning that clients support communicating with greater or equal minor versions of {{es}} without breaking. It does not mean that the client automatically supports new features of newer {{es}} versions; it is only possible after a release of a new client version. For example, a 8.12 client version won’t automatically support the new features of the 8.13 version of {{es}}, the 8.13 client version is required for that. {{es}} language clients are only backwards compatible with default distributions and without guarantees made.
-
-| {{es}} Version | Client Version | Supported |
-| --- | --- | --- |
-| `8.x` | `8.x` | `8.x` |
-| `7.x` | `7.x` | `7.17` |
-| `6.x` | `6.x` |  |
-| `5.x` | `5.x` |  |
-
-
-### Browser [_browser]
-
-::::{warning}
-There is no official support for the browser environment. It exposes your {{es}} instance to everyone, which could lead to security issues. We recommend you to write a lightweight proxy that uses this client instead, you can see a proxy example [here](https://github.com/elastic/elasticsearch-js/tree/master/docs/examples/proxy).

+[[client-testing]]
+=== Testing
+
+Testing is one of the most important parts of developing an application.
+The client is very flexible when it comes to testing and is compatible with
+most testing frameworks (such as https://www.npmjs.com/package/ava[`ava`],
+which is used in the examples below).
+
+If you are using this client, you are most likely working with {es}, and one of 
+the first issues you face is how to test your application. A perfectly valid 
+solution is to use the real {es} instance for testing your application, but you 
+would be doing an integration test, while you want a unit test. There are many 
+ways to solve this problem, you could create the database with Docker, or use an 
+in-memory compatible one, but if you are writing unit tests that can be easily 
+parallelized this becomes quite uncomfortable. A different way of improving your 
+testing experience while doing unit tests is to use a mock.
+
+The client is designed to be easy to extend and adapt to your needs. Thanks to 
+its internal architecture it allows you to change some specific components while 
+keeping the rest of it working as usual. Each {es} official client is composed 
+of the following components:
+
+* `API layer`: every {es} API that you can call.
+* `Transport`: a component that takes care of preparing a request before sending 
+  it and handling all the retry and sniffing strategies.
+* `ConnectionPool`: {es} is a cluster and might have multiple nodes, the 
+  `ConnectionPool` takes care of them.
+* `Serializer`: A class with all the serialization strategies, from the basic 
+  JSON to the new line delimited JSON.
+* `Connection`: The actual HTTP library.
+
+The best way to mock {es} with the official clients is to replace the 
+`Connection` component since it has very few responsibilities and it does not 
+interact with other internal components other than getting requests and 
+returning responses.
+
+
+[discrete]
+==== `@elastic/elasticsearch-mock`
+
+Writing each time a mock for your test can be annoying and error-prone, so we 
+have built a simple yet powerful mocking library specifically designed for this 
+client, and you can install it with the following command:
+
+[source,sh]
+----
+npm install @elastic/elasticsearch-mock --save-dev
+----
+
+With this library you can create custom mocks for any request you can send to 
+{es}. It offers a simple and intuitive API and it mocks only the HTTP layer, 
+leaving the rest of the client working as usual.
+
+Before showing all of its features, and what you can do with it, let’s see an 
+example:
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const Mock = require('@elastic/elasticsearch-mock')
+
+const mock = new Mock()
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' },
+  Connection: mock.getConnection()
+})
+
+mock.add({
+  method: 'GET',
+  path: '/'
+}, () => {
+  return { status: 'ok' }
+})
+
+client.info().then(console.log, console.log)
+----
+
+As you can see it works closely with the client itself, once you have created a 
+new instance of the mock library you just need to call the mock.getConnection()
+method and pass its result to the Connection option of the client. From now on, 
+every request is handled by the mock library,  and the HTTP layer will never be 
+touched. As a result, your test is significantly faster and you are able to 
+easily parallelize them!
+
+The library allows you to write both “strict” and “loose” mocks, which means 
+that you can write a mock that handles a very specific request or be looser and 
+handle a group of request, let’s see this in action:
+
+[source,js]
+----
+mock.add({
+  method: 'POST',
+  path: '/indexName/_search'
+}, () => {
+  return {
+    hits: {
+      total: { value: 1, relation: 'eq' },
+      hits: [{ _source: { baz: 'faz' } }]
+    }
+  }
+})
+
+mock.add({
+  method: 'POST',
+  path: '/indexName/_search',
+  body: { query: { match: { foo: 'bar' } } }
+}, () => {
+  return {
+    hits: {
+      total: { value: 0, relation: 'eq' },
+      hits: []
+    }
+  }
+})
+----
+
+In the example above, every search request gets the first response, while every 
+search request that uses the query described in the second mock gets the second 
+response.
+
+You can also specify dynamic paths:
+
+[source,js]
+----
+mock.add({
+  method: 'GET',
+  path: '/:index/_count'
+}, () => {
+  return { count: 42 }
+})
+
+client.count({ index: 'foo' }).then(console.log, console.log) // => { count: 42 }
+client.count({ index: 'bar' }).then(console.log, console.log) // => { count: 42 }
+----
+
+And wildcards are supported as well.
+
+Another very interesting use case is the ability to create a test that randomly
+fails to see how your code reacts to failures:
+
+[source,js]
+----
+mock.add({
+  method: 'GET',
+  path: '/:index/_count'
+}, () => {
+  if (Math.random() > 0.8) {
+    return ResponseError({ body: {}, statusCode: 500 })
+  } else {
+    return { count: 42 }
+  }
+})
+----
+
+We have seen how simple is mocking {es} and testing your application, you can 
+find many more features and examples in the 
+https://github.com/elastic/elasticsearch-js-mock[module documentation].

docs/timeout-best-practices.asciidoc

+[[timeout-best-practices]]
+=== Timeout best practices
+
+This client is configured by default to operate like many HTTP client libraries do, by using a relatively short (30 second) timeout on all requests sent to {es}, raising a `TimeoutError` when that time period has elapsed without receiving a response. However, {es} will always eventually respond to any request, even if it takes several minutes. The {ref}/modules-network.html#_http_client_configuration[official {es} recommendation] is to disable response timeouts entirely by default.
+
+Since changing this default would be a breaking change, we won't do that until the next major release. In the meantime, here is our recommendation for properly configuring your client:
+
+* Ensure keep-alive is enabled; this is the default, so no settings need to be changed, unless you have set `agent` to `false` or provided an alternate `agent` that disables keep-alive
+* If using the default `UndiciConnection`, disable request timeouts by setting `timeout` to `0`
+* If using the legacy `HttpConnection`, set `timeout` to a very large number (e.g. `86400000`, or one day)

 You can import the full TypeScript requests & responses definitions as it follows:
 
-```ts
+[source,ts]
+----
 import { estypes } from '@elastic/elasticsearch'
-```
+----
 
 If you need the legacy definitions with the body, you can do the following:
 
-```ts
+[source,ts]
+----
 import { estypesWithBody } from '@elastic/elasticsearch'
-```

     * Forget a follower. Remove the cross-cluster replication follower retention leases from the leader. A following index takes out retention leases on its leader index. These leases are used to increase the likelihood that the shards of the leader index retain the history of operations that the shards of the following index need to run replication. When a follower index is converted to a regular index by the unfollow API (either by directly calling the API or by index lifecycle management tasks), these leases are removed. However, removal of the leases can fail, for example when the remote cluster containing the leader index is unavailable. While the leases will eventually expire on their own, their extended existence can cause the leader index to hold more history than necessary and prevent index lifecycle management from performing some operations on the leader index. This API exists to enable manually removing the leases when the unfollow API is unable to do so. NOTE: This API does not stop replication by a following index. If you use this API with a follower index that is still actively following, the following index will add back retention leases on the leader. The only purpose of this API is to handle the case of failure to remove the following retention leases after the unfollow API is invoked.

By default, if there are more than three master-eligible nodes in the cluster and you remove fewer than half of the master-eligible nodes in the cluster at once, the voting configuration automatically shrinks. If you want to shrink the voting configuration to contain fewer than three nodes or to remove half or more of the master-eligible nodes in the cluster at once, use this API to remove departing nodes from the voting configuration manually. The API adds an entry for each specified node to the cluster’s voting configuration exclusions list. It then waits until the cluster has reconfigured its voting configuration to exclude the specified nodes. Clusters should have no voting configuration exclusions in normal operation. Once the excluded nodes have stopped, clear the voting configuration exclusions with `DELETE /_cluster/voting_config_exclusions`. This API waits for the nodes to be fully removed from the cluster before it returns. If your cluster has voting configuration exclusions for nodes that you no longer intend to remove, use `DELETE /_cluster/voting_config_exclusions?wait_for_removal=false` to clear the voting configuration exclusions without waiting for the nodes to leave the cluster. A response to `POST /_cluster/voting_config_exclusions` with an HTTP status code of 200 OK guarantees that the node has been removed from the voting configuration and will not be reinstated until the voting configuration exclusions are cleared by calling `DELETE /_cluster/voting_config_exclusions`. If the call to `POST /_cluster/voting_config_exclusions` fails or returns a response with an HTTP status code other than 200 OK then the node may not have been removed from the voting configuration. In that case, you may safely retry the call. NOTE: Voting exclusions are required only when you remove at least half of the master-eligible nodes from a cluster in a short time period. They are not required when removing master-ineligible nodes or when removing fewer than half of the master-eligible nodes.

You can also configure dynamic settings locally on an unstarted or shut down node in `elasticsearch.yml`. Updates made with this API can be persistent, which apply across cluster restarts, or transient, which reset after a cluster restart. You can also reset transient or persistent settings by assigning them a null value. If you configure the same setting using multiple methods, Elasticsearch applies the settings in following order of precedence: 1) Transient setting; 2) Persistent setting; 3) `elasticsearch.yml` setting; 4) Default setting value. For example, you can apply a transient setting to override a persistent setting or `elasticsearch.yml` setting. However, a change to an `elasticsearch.yml` setting will not override a defined transient or persistent setting. TIP: In Elastic Cloud, use the user settings feature to configure all cluster settings. This method automatically rejects unsafe settings that could break your cluster. If you run Elasticsearch on your own hardware, use this API to configure dynamic cluster settings. Only use `elasticsearch.yml` for static cluster settings and node settings. The API doesn’t require a restart and ensures a setting’s value is the same on all nodes. WARNING: Transient cluster settings are no longer recommended. Use persistent cluster settings instead. If a cluster becomes unstable, transient settings can clear unexpectedly, resulting in a potentially undesired cluster configuration.

     * Reroute the cluster. Manually change the allocation of individual shards in the cluster. For example, a shard can be moved from one node to another explicitly, an allocation can be canceled, and an unassigned shard can be explicitly allocated to a specific node. It is important to note that after processing any reroute commands Elasticsearch will perform rebalancing as normal (respecting the values of settings such as `cluster.routing.rebalance.enable`) in order to remain in a balanced state. For example, if the requested allocation includes moving a shard from node1 to node2 then this may cause a shard to be moved from node2 back to node1 to even things out. The cluster can be set to disable allocations using the `cluster.routing.allocation.enable` setting. If allocations are disabled then the only allocations that will be performed are explicit ones given using the reroute command, and consequent allocations due to rebalancing. The cluster will attempt to allocate a shard a maximum of `index.allocation.max_retries` times in a row (defaults to `5`), before giving up and leaving the shard unallocated. This scenario can be caused by structural problems such as having an analyzer which refers to a stopwords file which doesn’t exist on all nodes. Once the problem has been corrected, allocation can be manually retried by calling the reroute API with the `?retry_failed` URI query parameter, which will attempt a single retry round for these shards.

     * Get the cluster state. Get comprehensive information about the state of the cluster. The cluster state is an internal data structure which keeps track of a variety of information needed by every node, including the identity and attributes of the other nodes in the cluster; cluster-wide settings; index metadata, including the mapping and settings for each index; the location and status of every shard copy in the cluster. The elected master node ensures that every node in the cluster has a copy of the same cluster state. This API lets you retrieve a representation of this internal state for debugging or diagnostic purposes. You may need to consult the Elasticsearch source code to determine the precise meaning of the response. By default the API will route requests to the elected master node since this node is the authoritative source of cluster states. You can also retrieve the cluster state held on the node handling the API request by adding the `?local=true` query parameter. Elasticsearch may need to expend significant effort to compute a response to this API in larger clusters, and the response may comprise a very large quantity of data. If you use this API repeatedly, your cluster may become unstable. WARNING: The response is a representation of an internal data structure. Its format is not subject to the same compatibility guarantees as other more stable APIs and may change from version to version. Do not query this API using external monitoring tools. Instead, obtain the information you require using other more stable cluster APIs.

 /**
   * Delete a document. Remove a JSON document from the specified index. NOTE: You cannot send deletion requests directly to a data stream. To delete a document in a data stream, you must target the backing index containing the document. **Optimistic concurrency control** Delete operations can be made conditional and only be performed if the last modification to the document was assigned the sequence number and primary term specified by the `if_seq_no` and `if_primary_term` parameters. If a mismatch is detected, the operation will result in a `VersionConflictException` and a status code of `409`. **Versioning** Each document indexed is versioned. When deleting a document, the version can be specified to make sure the relevant document you are trying to delete is actually being deleted and it has not changed in the meantime. Every write operation run on a document, deletes included, causes its version to be incremented. The version number of a deleted document remains available for a short time after deletion to allow for control of concurrent operations. The length of time for which a deleted document's version remains available is determined by the `index.gc_deletes` index setting. **Routing** If routing is used during indexing, the routing value also needs to be specified to delete a document. If the `_routing` mapping is set to `required` and no routing value is specified, the delete API throws a `RoutingMissingException` and rejects the request. For example: ``` DELETE /my-index-000001/_doc/1?routing=shard-1 ``` This request deletes the document with ID 1, but it is routed based on the user. The document is not deleted if the correct routing is not specified. **Distributed** The delete operation gets hashed into a specific shard ID. It then gets redirected into the primary shard within that ID group and replicated (if needed) to shard replicas within that ID group.

If the document doesn’t exist, the API returns `404 - Not Found`. **Versioning support** You can use the `version` parameter to check the document only if its current version is equal to the specified one.

You can use this API to determine which feature states to include when taking a snapshot. By default, all feature states are included in a snapshot if that snapshot includes the global state, or none if it does not. A feature state includes one or more system indices necessary for a given feature to function. In order to ensure data integrity, all system indices that comprise a feature state are snapshotted and restored together. The features listed by this API are a combination of built-in features and features defined by plugins. In order for a feature state to be listed in this API and recognized as a valid feature state by the create snapshot API, the plugin that defines that feature must be installed on the master node.

 /**
   * Get a document by its ID. Get a document and its source or stored fields from an index. By default, this API is realtime and is not affected by the refresh rate of the index (when data will become visible for search). In the case where stored fields are requested with the `stored_fields` parameter and the document has been updated but is not yet refreshed, the API will have to parse and analyze the source to extract the stored fields. To turn off realtime behavior, set the `realtime` parameter to false. **Source filtering** By default, the API returns the contents of the `_source` field unless you have used the `stored_fields` parameter or the `_source` field is turned off. You can turn off `_source` retrieval by using the `_source` parameter: ``` GET my-index-000001/_doc/0?_source=false ``` If you only need one or two fields from the `_source`, use the `_source_includes` or `_source_excludes` parameters to include or filter out particular fields. This can be helpful with large documents where partial retrieval can save on network overhead Both parameters take a comma separated list of fields or wildcard expressions. For example: ``` GET my-index-000001/_doc/0?_source_includes=*.id&_source_excludes=entities ``` If you only want to specify includes, you can use a shorter notation: ``` GET my-index-000001/_doc/0?_source=*.id ``` **Routing** If routing is used during indexing, the routing value also needs to be specified to retrieve a document. For example: ``` GET my-index-000001/_doc/2?routing=user1 ``` This request gets the document with ID 2, but it is routed based on the user. The document is not fetched if the correct routing is not specified. **Distributed** The GET operation is hashed into a specific shard ID. It is then redirected to one of the replicas within that shard ID and returns the result. The replicas are the primary shard and its replicas within that shard ID group. This means that the more replicas you have, the better your GET scaling will be. **Versioning support** You can use the `version` parameter to retrieve the document only if its current version is equal to the specified one. Internally, Elasticsearch has marked the old document as deleted and added an entirely new document. The old version of the document doesn't disappear immediately, although you won't be able to access it. Elasticsearch cleans up deleted documents in the background as you continue to index more data.
