For fetching data from multiple indices, i am trying to use SearchResponse client. But while creating transportClient i get instantiate error. What wrong i am doing?
Following is my code snippet:
> public void setup() throws Exception {
> Client client = new TransportClient()
> .addTransportAddress(new InetSocketTransportAddress(
> "localhost", 9300));}
and SearchResponse code is:
> SearchResponse response = client.prepareSearch(index).setTypes(type).setQuery(QueryBuilders.wrapperQuery(query))
> .execute().actionGet();
One more doubt can we use jest client for multiple indices search?
I am using elasticsearch version 6.2.

Here is the documentation: [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html)
But you should move to the Rest client instead: [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html)

I am trying to perform multiple indices search and i don't find anything like prespareSearch() in rest high level client. But you can suggest me what i can use in restHighLevelClient. I followed [[https://www.elastic.co/guide/en/elasticsearch/client/java-api/6.2/java-search.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/6.2/java-search.html)] link and got to know that prepare search only works with transport client.

Did you read the documentation? [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-search.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-search.html)

I read about multi-search and i am tried using same in ES 6.2, but when i am sending request like:
> MultiSearchResponse response = client.msearch(request, RequestOptions.DEFAULT);
I get error on RequestOptions cannot be resolved to a variable, where is RequestOption class?

I think that multisearch is only available from 6.3.
It's not part of the documentation of 6.2: [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.2/index.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.2/index.html)
But you can use the Rest client 6.3 with elasticsearch 6.2.
Or better upgrade your server to elasticsearch 6.3.

I am very much eager to know, how to use rest client 6.3 with ES 6.2 is there any documentation on that?

You are asking for documentation but I feel like you are reading it.
So here we go again: [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-compatibility.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-compatibility.html)
