 ## Automatic product check [product-check]
 
 Since v7.14.0, the client performs a required product check before the first call.

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.

+# Timeout best practices [timeout-best-practices]
+
+Starting in 9.0.0, this client is configured to not time out any HTTP request by default. {{es}} will always eventually respond to any request, even if it takes several minutes. Reissuing a request that it has not responded to yet can cause performance side effects. See the [official {{es}} recommendations for HTTP clients](elasticsearch://reference/elasticsearch/configuration-reference/networking-settings.md#_http_client_configuration) for more information.
+
+Prior to 9.0, this client was 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 elapsed without receiving a response.
+
+If you need to set timeouts on Elasticsearch requests, setting the `requestTimeout` value to a millisecond value will cause this client to operate as it did prior to 9.0.

-% ::::
+::::{dropdown} Changes to the optional body property
+
+In 8.x, every API function had a `body` property that would provide a place to put arbitrary values that should go in the HTTP request body, even if they were not noted in the specification or documentation. In 9.0, each API function still includes an optional `body` property, but TypeScript's type checker will disallow properties that should go in the root of the object. A `querystring` parameter has also been added that behaves the same as `body`, but inserts its values into the request querystring.
+
+**Impact**<br> Some adjustments to API calls may be necessary for code that used a `body` property 8.x, especially to appease the TypeScript type checker, but it should not have any impact on any code that was not using a `body` property. The `estypesWithBody` export and `typesWithBodyKey` module are no longer available.
+
+**Action**<br> Check existing code for use of the `body` property, and move any properties that should be in the root object according to the API function's request type definition. If using TypeScript, the TypeScript type checker will surface most of these issues for you. Also look for any imports of `estypesWithBody` or `typesWithBodyKey` and update them to `estypes` and `types`, respectively.
+::::
+
+::::{dropdown} Changes to API parameter collation into an HTTP request
+
+The logic for where each parameter in an API function call should be added to its HTTP request has been updated:
+
+1. If recognized as a `body` parameter according to the Elasticsearch specification, put it in the JSON body
+2. If recognized as a `path` parameter, put it in the URL path
+3. If recognized as a `query` parameter or a "common" query parameter (e.g. `pretty`, `error_trace`), put it in the querystring
+4. If not recognized, and this API accepts a JSON body, put it in the JSON body
+5. If not recognized and this API does not accept a JSON body, put it in the querystring
+
+The first two steps are identical in 8.x. The final three steps replace the logic from 8.x that put all unrecognized parameters in the querystring.
+
+**Impact**<br> Some parameters that were sent via querystring to Elasticsearch may be sent in the JSON request body, and vice versa.
+
+**Action**<br> If Elasticsearch sends back an error response due to a request not being valid, verify with the client's TypeScript type definitions, or via the docs, that the parameters your code passes are correct.
+::::
+
+::::{dropdown} Removal of the default 30-second timeout on all API calls
+
+The default 30-second timeout on all HTTP requests sent to Elasticsearch has been dropped in favor of having no timeout set at all. The previous behavior still works as it did when setting the `requestTimeout` value.
+
+See pull request [#2573](https://github.com/elastic/elasticsearch-js/pull/2573) for more information.
+
+**Impact**<br> Requests to Elasticsearch that used to time out after 30 seconds will now wait for as long as it takes for Elasticsearch to respond.
+
+**Action**<br> In environments where it is not ideal to wait for an API response indefinitely, manually setting the `requestTimeout` option when instantiating the client still works as it did in 8.x.

+
+**Reinstate `nodeFilter` and node `roles` feature:** The docs note a `nodeFilter` option on the client that will, by default, filter the nodes based on any `roles` values that are set at instantiation. At some point, this functionality was partially disabled. This brings the feature back, ensuring that it matches what the documentation has said it does all along.
+
+**Ensure Apache Arrow ES|QL helper uses async iterator:** the [`esql.toArrowReader()` helper function](/reference/client-helpers.md#_toarrowreader) was trying to return `RecordBatchStreamReader`—a synchronous iterator—despite the fact that the `apache-arrow` package was, in most cases, automatically coercing it to `AsyncRecordBatchStreamReader`, its asynchronous counterpart. It now is always returned as an async iterator.
+
+## 9.0.0 [elasticsearch-javascript-client-9.0.0-release-notes]
+
+### Features and enhancements [elasticsearch-javascript-client-9.0.0-features-enhancements]
+
+- **Compatibility with Elasticsearch 9.0:** All changes and additions to Elasticsearch APIs for its 9.0 release are reflected in this release.
+- **Serverless client merged in:** the `@elastic/elasticsearch-serverless` client is being deprecated, and its functionality has been merged back into this client. This should have zero impact on the way the client works by default, except that a new `serverMode` option has been added. When it's explicitly set to `"serverless"` by a user, a few default settings and behaviors are changed:
+
+  - turns off sniffing and ignores any sniffing-related options
+  - ignores all nodes passed in config except the first one, and ignores any node filtering and selecting options
+  - enables compression and `TLSv1_2_method` (same as when configured for Elastic Cloud)
+  - adds an `elastic-api-version` HTTP header to all requests
+  - uses `CloudConnectionPool` by default instead of `WeightedConnectionPool`
+  - turns off vendored `content-type` and `accept` headers in favor or standard MIME types
+
+  Docstrings for types that differ between stack and serverless have also been updated to indicate when that is the case.
+
+- **Improved Cloud ID parsing:** when using a Cloud ID as the `cloud` parameter to instantiate the client, that ID was assumed to be in the correct format. New assertions have been added to verify that format and throw a `ConfigurationError` if it is invalid. See [#2694](https://github.com/elastic/elasticsearch-js/issues/2694).

-  == API Reference
-
-  This document contains the entire list of the Elasticsearch API supported by the client, both OSS and commercial. The client is entirely licensed under Apache 2.0.
-
-  Elasticsearch exposes an HTTP layer to communicate with, and the client is a library that will help you do this. Because of this reason, you will see HTTP related parameters, such as ${'`'}body${'`'} or ${'`'}headers${'`'}.
-
-  Every API can accept two objects, the first contains all the parameters that will be sent to Elasticsearch, while the second includes the request specific parameters, such as timeouts, headers, and so on.
-  In the first object, every parameter but the body will be sent via querystring or url parameter, depending on the API, and every unrecognized parameter will be sent as querystring.
-
-  [source,js]
-  ----
-  // promise API
-  const result = await client.search({
-    index: 'my-index',
-    from: 20,
-    size: 10,
-    body: { foo: 'bar' }
-  }, {
-    ignore: [404],
-    maxRetries: 3
-  })
-
-  // callback API
-  client.search({
-    index: 'my-index',
-    from: 20,
-    size: 10,
-    body: { foo: 'bar' }
-  }, {
-    ignore: [404],
-    maxRetries: 3
-  }, (err, result) => {
-    if (err) console.log(err)
-  })
-  ----
-
-  In this document, you will find the reference of every parameter accepted by the querystring or the url. If you also need to send the body, you can find the documentation of its format in the reference link that is present along with every endpoint.

The `required_capacity` is calculated as the maximum of the `required_capacity` result of all individual deciders that are enabled for the policy. The operator should verify that the `current_nodes` match the operator’s knowledge of the cluster to avoid making autoscaling decisions based on stale or incomplete information.

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.

     * Update voting configuration exclusions. Update the cluster voting config exclusions by node IDs or node names. 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.

 /**
   * 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.

   * Check a document. Verify that a document exists. For example, check to see if a document with the `_id` 0 exists: ``` HEAD my-index-000001/_doc/0 ``` If the document exists, the API returns a status code of `200 - OK`. 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. 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.

 /**
   * 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.

   * Get the cluster health. Get a report with the health status of an Elasticsearch cluster. The report contains a list of indicators that compose Elasticsearch functionality. Each indicator has a health status of: green, unknown, yellow or red. The indicator will provide an explanation and metadata describing the reason for its current health status. The cluster’s status is controlled by the worst indicator status. In the event that an indicator’s status is non-green, a list of impacts may be present in the indicator result which detail the functionalities that are negatively affected by the health issue. Each impact carries with it a severity level, an area of the system that is affected, and a simple description of the impact on the system. Some health indicators can determine the root cause of a health problem and prescribe a set of steps that can be performed in order to improve the health of the system. The root cause and remediation steps are encapsulated in a diagnosis. A diagnosis contains a cause detailing a root cause analysis, an action containing a brief description of the steps to take to fix the problem, the list of affected resources (if applicable), and a detailed step-by-step troubleshooting guide to fix the diagnosed problem. NOTE: The health indicators perform root cause analysis of non-green health statuses. This can be computationally expensive when called frequently. When setting up automated polling of the API for health status, set verbose to false to disable the more expensive analysis logic.

If only the phase is specified, the index will move to the first step of the first action in the target phase. If the phase and action are specified, the index will move to the first step of the specified action in the specified phase. Only actions specified in the ILM policy are considered valid. An index cannot move to a step that is not part of its policy.

 /**
-  * Run a knn search. NOTE: The kNN search API has been replaced by the `knn` option in the search API. Perform a k-nearest neighbor (kNN) search on a dense_vector field and return the matching documents. Given a query vector, the API finds the k closest vectors and returns those documents as search hits. Elasticsearch uses the HNSW algorithm to support efficient kNN search. Like most kNN algorithms, HNSW is an approximate method that sacrifices result accuracy for improved search speed. This means the results returned are not always the true k closest neighbors. The kNN search API supports restricting the search using a filter. The search will return the top k documents that also match the filter query. A kNN search response has the exact same structure as a search API response. However, certain sections have a meaning specific to kNN search: * The document `_score` is determined by the similarity between the query and document vector. * The `hits.total` object contains the total number of nearest neighbor candidates considered, which is `num_candidates * num_shards`. The `hits.total.relation` will always be `eq`, indicating an exact value.

 /**
   * Open a point in time. A search request by default runs against the most recent visible data of the target indices, which is called point in time. Elasticsearch pit (point in time) is a lightweight view into the state of the data as it existed when initiated. In some cases, it’s preferred to perform multiple search requests using the same point in time. For example, if refreshes happen between `search_after` requests, then the results of those requests might not be consistent as changes happening between searches are only visible to the more recent point in time. A point in time must be opened explicitly before being used in search requests. A subsequent search request with the `pit` parameter must not specify `index`, `routing`, or `preference` values as these parameters are copied from the point in time. Just like regular searches, you can use `from` and `size` to page through point in time search results, up to the first 10,000 hits. If you want to retrieve more hits, use PIT with `search_after`. IMPORTANT: The open point in time request and each subsequent search request can return different identifiers; always use the most recently received ID for the next search request. When a PIT that contains shard failures is used in a search request, the missing are always reported in the search response as a `NoShardAvailableActionException` exception. To get rid of these exceptions, a new PIT needs to be created so that shards missing from the previous PIT can be handled, assuming they become available in the meantime. **Keeping point in time alive** The `keep_alive` parameter, which is passed to a open point in time request and search request, extends the time to live of the corresponding point in time. The value does not need to be long enough to process all data — it just needs to be long enough for the next request. Normally, the background merge process optimizes the index by merging together smaller segments to create new, bigger segments. Once the smaller segments are no longer needed they are deleted. However, open point-in-times prevent the old segments from being deleted since they are still in use. TIP: Keeping older segments alive means that more disk space and file handles are needed. Ensure that you have configured your nodes to have ample free file handles. Additionally, if a segment contains deleted or updated documents then the point in time must keep track of whether each document in the segment was live at the time of the initial search request. Ensure that your nodes have sufficient heap space if you have many open point-in-times on an index that is subject to ongoing deletes or updates. Note that a point-in-time doesn't prevent its associated indices from being deleted. You can check how many point-in-times (that is, search contexts) are open with the nodes stats API.
