Hi,

How do I check if index exist in JAVA API 8.2.

In v.7.x I used:

```auto
GetIndexRequest request = new GetIndexRequest("yourindexname");
restHighLevelclient.indices().exists(request, RequestOptions.DEFAULT);

```

RestHighLevelClient is deprecated in 8.2 so I cant use client.indices().exists.  
RestHighLevelClient is changed to RestClient.

what is the client object in:

```auto
var result = client.indices().exists(ExistsRequest.of(e -> e.index("name_index")));

```

I just find out that the new way is:

````auto
Response response = client.performRequest(new Request("HEAD", "/" + index));
	return response.getStatusLine().getStatusCode() == 200;```
````

You are using low-level client.

My code:

```
RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200)).build();
ElasticsearchTransport transport = new RestClientTransport(restClient, new JacksonJsonpMapper());
ElasticsearchClient client = new ElasticsearchClient(transport);
BooleanResponse result = client.indices().exists(ExistsRequest.of(e -> e.index("xpto")));
System.out.println("Exists indices: " + result.value());

```
