Rob Audenaerde updated LUCENE-5474:
-----------------------------------

    Description: 
In the examples of facetting the {{FacetsCollector.search()}} is used. There 
are use cases where you do not need the documents that match the search. 
It would be nice if there is an example showing this.

Basically, it comes down to using {{searcher.search(query, null /* Filter */, 
facetCollector}}
