Adrien Grand reopened LUCENE-6458:
----------------------------------
I just noticed that while my changes helped rewrite to a BooleanQuery and use
BS2 whenever possible, they never propagate BS1 as a bulk scorer.
> MultiTermQuery's FILTER rewrite method should support skipping whenever
> possible

> Today MultiTermQuery's FILTER rewrite always builds a bit set fom all
> matching terms. This means that we need to consume the entire postings lists
> of all matching terms. Instead we should try to execute like regular
> disjunctions when there are few terms.
