Java API for filter_path in elastic search

Elastic Stack Elasticsearch
1

Hi,
I need to reduce the response size of elastic search query, So I found one way to use Response Filtering through filter_path parameter in URL.

GET testindex-2016.04.14/_search?filter_path=aggregations.testAggs.buckets

Below is the link:
https://www.elastic.co/guide/en/elasticsearch/reference/2.3/common-options.html#_response_filtering

But I couldn't find any way to implement response filtering in Java API,
While googling, I have also seen one FilterPath.java class in elastic search, but I couldn't find any example of it. Even I am not sure whether this class can be used for this purpose or not.

Please suggest me any way to implement response filtering in Java. Thanks

The Transport Client can not do that. It's done on a REST level.

It's done here:
