Handle bulk errors in examples

The ingest docs in Elasticsearch doing point to the actual ingest APIs.
This makes up generate links to the real APIs instead, fixing some
broken links in the 5.x docs in the process.

-**Note:** In the past months we have worked on the new Elasticsearch Node.js client and you can use it by following the instructions below. If you're going to use the legacy one or report an issue, however, please check out [elastic/elasticsearch-js-legacy](https://github.com/elastic/elasticsearch-js-legacy).

 ## Features
 - One-to-one mapping with REST API.
 - Generalized, pluggable architecture.
 - Configurable, automatic discovery of cluster nodes.
 - Persistent, Keep-Alive connections.
-- Load balancing across all available nodes.
-- Child client support.
+- Load balancing (with pluggable selection strategy) across all available nodes.
 - TypeScript support out of the box.
 
 ## Install
@@ -28,51 +28,30 @@ npm install @elastic/elasticsearch
 
 ### Compatibility
 
-The minimum supported version of Node.js is `v8`.
+---
 
-The library is compatible with all Elasticsearch versions since 5.x, and you should use the same major version of the Elasticsearch instance that you are using.
+**Warning:** currently on npm you will only find a beta release that works with Elasticsearch 7, we will add the support for Elasticsearch 5, 6, and 7 once we release the final version of this library.
 
-| Elasticsearch Version | Client Version |
-| --------------------- |----------------|
-| `master`              | `master`       |
-| `7.x`                 | `7.x`          |
-| `6.x`                 | `6.x`          |
-| `5.x`                 | `5.x`          |

-To install a specific major of the client, run the following command:
+The library is compatible with all Elasticsearch versions since 5.x, but you should use the same major version of the Elasticsearch instance that you are using.
 ```
-npm install @elastic/elasticsearch@<major>

 ```
 
-#### Browser
-
-WARNING: There is no official support for the browser environment. It exposes your Elasticsearch instance to everyone, which could lead to security issues.
-We recommend that you write a lightweight proxy that uses this client instead.

-## Install multiple versions
-If you are using multiple versions of Elasticsearch, you need to use multiple versions of the client. In the past, install multiple versions of the same package was not possible, but with `npm v6.9`, you can do that via aliasing.
-
-The command you must run to install different version of the client is:
-```sh
-npm install <alias>@npm:@elastic/elasticsearch@<version>
-```
-So for example if you need to install `7.x` and `6.x`, you will run
-```sh
-npm install es6@npm:@elastic/elasticsearch@6
-npm install es7@npm:@elastic/elasticsearch@7
-```
-And your `package.json` will look like the following:
-```json
-"dependencies": {
-  "es6": "npm:@elastic/elasticsearch@^6.7.0",
-  "es7": "npm:@elastic/elasticsearch@^7.0.0"
+### Client options
+The client is designed to be easily configured as you see fit for your needs, following you can see all the possible options that you can use to configure it.
+```ts
+{
+  // the Elasticsearch endpoint to use
+  node: string | string[];
+  // alias of above
+  nodes: string | string[];
+  // custom connection class
+  Connection: typeof Connection;
+  // custom connection pool class
+  ConnectionPool: typeof ConnectionPool;
+  // custom transport class
+  Transport: typeof Transport;
+  // custom serializer class
+  Serializer: typeof Serializer;
+  // max number of retries for each request
+  maxRetries: number;
+  // max request timeout for each request
+  requestTimeout: number;
+  // max ping timeout for each request
+  pingTimeout: number;
+  // perform a sniff operation every `n` milliseconds
+  sniffInterval: number;
+  // perform a sniff once the client is started
+  sniffOnStart: boolean;
+  // custom sniff endpoint, defaults `_nodes/_all/http`
+  sniffEndpoint: string;
+  // perform a sniff on connection fault
+  sniffOnConnectionFault: boolean;
+  // configurethe node resurrection strategy, default `ping`
+  resurrectStrategy: 'ping' | 'optimistic' | 'none';
+  // adds `accept-encoding` header to every request
+  suggestCompression: boolean;
+  // enable gzip request body compression
+  compression: 'gzip';
+  // ssl configuraton
+  ssl: http.SecureContextOptions;
+  // http agent options
+  agent: http.AgentOptions;
+  // filters which node not to use for a request
+  nodeFilter: nodeFilterFn;
+  // custom selection strategy, defaults `round-robin`
+  nodeSelector: nodeSelectorFn | string;
 }
 ```
-You will require the packages from your code by using the alias you have defined.
+
+### Request specific options
+If needed you can pass request specific options in a second object:
 ```js
-const { Client: Client6 } = require('es6')
-const { Client: Client7 } = require('es7')
-
-const client6 = new Client6({ node: 'http://localhost:9200' })
-const client7 = new Client7({ node: 'http://localhost:9201' })
-
-client6.info(console.log)
-client7.info(console.log)
+// promise API
+const result = await client.search({
+  index: 'my-index',
+  body: { foo: 'bar' }
+}, {
+  ignore: [404],
+  maxRetries: 3
+})
 ```
-
-Finally, if you want to install the client for the next version of Elasticsearch *(the one that lives in Elasticsearch’s master branch)*, you can use the following command:
-```sh
-npm install esmaster@github:elastic/elasticsearch-js
+The supported *request specific options* are:
+```ts
+{
+  ignore: [number], // default `null`
+  requestTimeout: number, // client default
+  maxRetries: number, // default `5`
+  asStream: boolean, // default `false`
+  compression: string, // default `false`
+  headers: object, // default `null`
+  querystring: object // default `null`
+}
 ```
