> 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)}}
