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?
