Description

"fq" filter queries that have cache=false and which aren't processed as a PostFilter (thus either aren't a PostFilter or have a cost < 100) are processed in SolrIndexSearcher using a custom Filter thingy which uses a cost-ordered series of DocIdSetIterators. This is not TwoPhaseIterator aware, and thus the match() method may be called on docs that ideally would have been filtered by lower-cost filter queries.
