[jira] [Updated] (LUCENE-4791) ConjunctionTermScorer scans instead
of skips on first scorer
[ https://issues.apache.org/jira/browse/LUCENE-4791?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yonik Seeley updated LUCENE-4791:
---------------------------------
Attachment: LUCENE-4791.patch
I rewrote the doNext() method, always using advance, and removing some other unnecessary checks (like NO_MORE_DOCS) that should slightly speed things up.
All tests pass.

> As discovered by John Wang, it looks like a bug was introduced when ConjunctionTermScorer was first introduced in 7/2011 that causes scanning instead of skipping on the lowest frequency term.
