As it can read from the oficial Java API documentation, We can set the "query_cache" param.
But, there is none method on CountRequestBuilder to set request params.
Which is the right way to set params in request from Java API?, specially for the exposed kind, the Count request.
Count api has been removed.
The deprecated count api has been removed from the Java api, use the search api instead and set size to 0.
The following call
client.prepareCount(indices).setQuery(query).get();
can be replaced with
client.prepareSearch(indices).setSource(new SearchSourceBuilder().size(0).query(query)).get();
Here is one example for running a count query with Java:
CountResponse response = client.prepareCount(INDEX)
.setQuery(new TermQueryBuilder("_type", TYPE))
.execute()
.actionGet();
As me said in #1, CountRequestBuilder doesn't has any way to specify "query_cache" param, the only one way to achieve this approach is working with SearchRequestBuilder in this way.
this.transportClient.prepareSearch(...).setTypes(...)
.setSearchType(SearchType.COUNT)
.setQuery(...)
.setQueryCache(true)
.execute().actionGet();
