Subject [jira] [Created] (LUCENE-6260) Simplify ExactPhraseScorer
Date Thu, 19 Feb 2015 09:44:11 GMT
Adrien Grand created LUCENE-6260:
------------------------------------

             Summary: Simplify ExactPhraseScorer
                 Key: LUCENE-6260
                 URL: https://issues.apache.org/jira/browse/LUCENE-6260
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand
            Priority: Minor


ExactPhraseScorer tries to intersect positions using windows of 4096 documents. In LUCENE-2410
it was reported that it helped a lot but I tried again on wikibig with a simpler impl that
does advance one position at a time and the performance difference was only of a few percents.
I'm guessing that maybe other changes (eg. the new postings format?) do not make this behaviour
as useful as it used to be?
