Uwe Schindler updated LUCENE-3451: ---------------------------------- Attachment: LUCENE-3451.patch Attached a patch with some changes in the BooleanQuery prohibited-only detection and all failing tests fixed: - TestBoolean2 had a explicit prohibited-only query -> changed to assert the UOE - TestBoolean2 had a random BQ generator. Fixed this generator to not create prohibited-only queries - in TestComplexExplanations* the prohibited-only fake clauses were removed - MemoryIndexTest used a list of lots of query-strings, some of them looking like that : "a -b". If the test had randomly choosen a MockTokenizer with english stopwords -> peng. Removed that Analyzer The last example is one problem of the explicit UOE: Now a user can suddenly get UOE if he uses a query where e.g. all positive clauses are stopwords - ok, users were always confused about that. Any comments about that? > 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, LUCENE-3451.patch > > > We should at least in Lucene 4.0 remove the hack in BooleanFilter that allows > pure negative Filter clauses.
