Filtering Source using the Java API

I'm trying to limit my Java API-run Elasticsearch queries so that they only return some specific fields from _source.

The analogous query using the REST API looks like:

curl -X GET http://localhost:9200/ci_person/t/_search?q=name_s:ben&_source=name_s

How do I do this in Java?

searchRequestBuilder.addFields(<array of fields>); only returns set fields, but in doing so it completely changes the structure of the returned data (replacing _source with a nested field object). This isn't acceptable for what I'm doing, because specifying a set of fields to return shouldn't completely change what's returned.
