Subject [jira] Updated: (LUCENE-730) Restore top level disjunction performance
Date Fri, 25 May 2007 00:11:17 GMT

Michael Busch updated LUCENE-730:
---------------------------------

    Attachment: lucene-730.patch

With this patch the old BooleanScorer is only used if BooleanQuery.setUseScorer14(true) is
set. It also enables the tests in QueryUtils again that check if the docs are returned in
order.

All tests pass.
