[ http://issues.apache.org/jira/browse/LUCENE-730?page=all ]
Paul Elschot updated LUCENE-730:
--------------------------------
Attachment: TopLevelDisjunction20061127.patch
This patches BooleanScorer2 to use BooleanScorer in the score(HitCollector)
method.
This also patches BooleanScorer to accept a minimum number of optional matchers.
The patch also disables some test code: the use of checkSkipTo in QueryUtils
caused a test failure in TestBoolean2 with the above changes. I think this
could be expected because of the changed document scoring order
for top level disjunction queries.
At the moment I don't know how to resolve this.
With the complete patch, all tests pass here.
