Paul Elschot commented on LUCENE-1345:
--------------------------------------
bq. In my opinion, the terms "Query" and "Filter" should be merged.
There is clear distinction between the two terms.
QueryWrapperFilter changes a Query into a Filter and ConstantScoreQuery changes
a Filter into a Query.
The first one removes the scoring by upcasting a Scorer to a DocIdSetIterator,
and the second one adds a constant score to a DocIdSetIterator to create a
Scorer.
> Allow Filter as clause to BooleanQuery
