使用Elasticsearch Transport客户端指定字段

Question

Is there a way to specify the fields ES returns via Transport Client, specifically using BoolQueryBuilder?

With REST API, it seems easy, eg Can I specify the result fields in elasticsearch query?

But not sure how to do it with Transport Client. Looking at BoolQueryBuilder class, I don't see any definitions for fields.

Using Java your code should look something like this:

SearchResponse searchResponse = client.prepareSearch("yourindex")
        .setQuery(boolQuery().must(matchAllQuery(), ...))
        .addFields("field1","field2")
        .get();
