Use filtered query instead of filter in Elasticsearch

Browse source 
Summary:
The 'filter' works like this: Get all results matching query (all if there's no query), compute facets (if there are any) and then filter out the uninteresting results.
The 'filtered' query applies the filters when searching, not when processing results.
This is obviously not documented anywhere in the great Elasticsearch documentation.

We don't hit this problem very often as we usually use some query.

Test Plan: Searched for open documents using Elasticsearch, verified the sent JSON, verified results.
