> It's common for Elasticsearch to ingest time-based data where newer segments
> contain recent data and older segments contain older data. On such indices,
> it's common for range queries on the time field to match either all of or
> none of the documents in the segment.
> We could implement Weight#count on pure conjunctions to take advantage of
> this by either returning 0 if any of the clauses has a match count of 0, or
> the count of the only clause that doesn't have a match count that is equal to
> maxDoc.
