John Wang commented on LUCENE-5425:
-----------------------------------
Thanks Lei!
Shai, given that using OBS Iterator performance is the same as trunk, do you
think we should move forward and change to the DocIdSet api or do you still
think we should split up as 2 different issues.
Thanks and please advise.

> In FacetsCollector, creation of bits in MatchingDocs are allocated per query.
