Subject [jira] Created: (LUCY-117) More boolean Matchers.
Date Mon, 21 Jun 2010 05:27:24 GMT
More boolean Matchers.

                 Key: LUCY-117
             Project: Lucy
          Issue Type: New Feature
          Components: Core - Search
            Reporter: Marvin Humphrey
            Assignee: Marvin Humphrey
            Priority: Blocker

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.
