Is there a way in elasticsearch using JAVA API to get only the ids of the documents returned for a give query. ``` SearchResponse sr = ``` esClient.prepareSearch(index).setSize(resultSize).setQuery(q).setScroll(new TimeValue(10000)).setQuery(fqb).setFetchSource(false).get(); but I get empty hits (`sr.getHits().hits[].length == 0`) althouh the total count of returned hits is 0 (`sr.getHits().getTotalHits == 2`). I understand that nothing is returned by elasticsearch because I set fetch source to false, but the ids should somehow be available. My current solution is: ``` SearchResponse sr = ``` esClient.prepareSearch(index).setSize(resultSize).setQuery(q).setScroll(new TimeValue(10000)).setQuery(fqb).srb.setFetchSource("\_id", null).get(); However I think that gets the \_id field from source, and for speed I would like to avoid this if possible.

Have you tried setting no fields to be returned or the explicit setNoFields() method?
