Hi, I had a quick question about RangeFacetsCounts <https://github.com/apache/lucene/blob/a071180a806d1bb7ae11ae30a07e43e452bea810/lucene/facet/src/java/org/apache/lucene/facet/range/RangeFacetCounts.java#L65>, I'm a bit confused by the fastMatchQuery param. Specifically, I was wondering why we need this when we can provide hits from a FacetCollector directly without having to run a query? I realize that the fastMatchQuery is used for filtering provided hits further, but it seems redundant when we can do all the matching we need before providing the FacetCollector object to RangeFacetCounts. SortedSetDocValuesFacetCounts only has FacetCollector as a param for example <https://github.com/apache/lucene/blob/a071180a806d1bb7ae11ae30a07e43e452bea810/lucene/facet/src/java/org/apache/lucene/facet/sortedset/SortedSetDocValuesFacetCounts.java#L89> without having the fastMatchQuery param. Maybe I'm misunderstanding something here? If anyone has an explanation that would be super helpful!
Thanks! Marc D'Mello
