Subject [jira] Updated: (LUCENE-749) ChainedFilter does not work well in the event of filters in ANDNOT
Date Fri, 15 Dec 2006 18:58:22 GMT
     [ http://issues.apache.org/jira/browse/LUCENE-749?page=all ]

Antonio Bruno updated LUCENE-749:
---------------------------------

    Attachment: ChainedFilter.patch.txt

In this way it is avoided that the first ANDNOT operation takes place against a completely
false bitset and will always return zero results.
