> More boolean Matchers.
> ----------------------
>
> Key: LUCY-117
> URL: https://issues.apache.org/jira/browse/LUCY-117
> Project: Lucy
> Issue Type: New Feature
> Components: Core - Search
> Reporter: Marvin Humphrey
> Assignee: Marvin Humphrey
> Priority: Blocker
> Attachments: and_scorer.patch, not_scorer.patch, req_opt_scorer.patch
>
>
> ANDScorer, NOTScorer, and RequiredOptionalScorer all subclass PolyMatcher,
> like ORMatcher/ORScorer.
> These three matchers are much simpler to implement than ORMatcher/ORScorer:
> ORMatcher.c is longer than the other three .c files combined. OR-combining is
> simply much harder to do well when proceeding doc-at-a-time, and the optimized
> code in ORMatcher.c takes up more space.
