Michael McCandless commented on LUCENE-3451: -------------------------------------------- Patch looks great! I think we should also backport to 3.x? And advertise the breakage. If users hit this exception it means their current searches aren't working so it's a service for us to inform them of this. > Remove special handling of pure negative Filters in BooleanFilter, disallow > pure negative queries in BooleanQuery > ----------------------------------------------------------------------------------------------------------------- > > Key: LUCENE-3451 > URL: https://issues.apache.org/jira/browse/LUCENE-3451 > Project: Lucene - Java > Issue Type: Bug > Reporter: Uwe Schindler > Assignee: Uwe Schindler > Fix For: 4.0 > > Attachments: LUCENE-3451.patch, LUCENE-3451.patch > > > We should at least in Lucene 4.0 remove the hack in BooleanFilter that allows > pure negative Filter clauses.
