Hi,

I am trying to query on multiple indices using Java API. The wildcard expression is passed to the request like this

> ```
> String[] indices = client.indices().get(new GetIndexRequest().indices("prefix_*"), RequestOptions.DEFAULT).indices();
> 
> ```

```
SearchRequest searchRequest = new SearchRequest();
searchRequest.indices(indices);

```

but as this wildcard term expanded to a relatively large number of index (over 1000), it returned this error:

> `{"error":{"root_cause":[{"type":"too_long_frame_exception","reason":"An HTTP line is larger than 4096 bytes."}],"type":"too_long_frame_exception","reason":"An HTTP line is larger than 4096 bytes."},"status":400}`

When using kibana, it works perfectly as expected.

> GET prefix\_\*/\_search

How could it be done through Java API? I have been looking for proper solution from Java documentation but not found any.

Thanks in advance.
