    Description

      Today when you have MUST_NOT clauses, the ReqExclScorer is used and needs to check the excluded clauses on every iteration. I suspect we could speed things up by having a BulkScorer that would advance the excluded clause first and then tell the required clause to bulk score up to the next excluded document.
