[PATCH] Performance improvement for doNext() of ConjunctionScorer
-----------------------------------------------------------------

                 Key: LUCENE-640
                 URL: http://issues.apache.org/jira/browse/LUCENE-640
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Search
    Affects Versions: 2.0.0
            Reporter: Johan Stuyts
         Attachments: Lucene2ConjunctionScorerDoNextPerformance.patch

I was able to improve the performance of 'doNext() of 'ConjunctionScorer' by over 20% by storing
the result of some calls that were performed multiple times in local variables. The test program
invoked the method over 400,000 times on each run.

I ran the performance tests on: 
- Windows XP Pro SP2 
- Sun JDK 1.5.0_07 
- YourKit 5.5.4 
- Lucene trunk
