Hi,  
How do I use multisearch api in my java program through my LowLevelRest client and HighLEvel Rest Client??

I have referred the documentation but can't understand much of it!

With the Low Level client you have to do most of the job by yourself.

Something like:

```auto
Map<String, String> params = Collections.emptyMap();
String jsonString = "/* All your requests here */";
HttpEntity entity = new NStringEntity(jsonString, ContentType.APPLICATION_JSON);
Response response = restClient.performRequest("GET", "/_msearch", params, entity); 

```

And Similarly with HighLevel?  
Is there any performance different in both cases?

`_msearch` is not implemented yet. See
