Robert Muir resolved LUCENE-538. -------------------------------- Resolution: Fixed Fix Version/s: 3.1 This is now fixed by Mike's cleanup to MultiSearcher etc, which fixes this combine/rewrite bug > Using WildcardQuery with MultiSearcher, and Boolean MUST_NOT clause > ------------------------------------------------------------------- > > Key: LUCENE-538 > URL: https://issues.apache.org/jira/browse/LUCENE-538 > Project: Lucene - Java > Issue Type: Bug > Components: Search > Affects Versions: 1.9 > Environment: Ubuntu Linux, java version 1.5.0_04 > Reporter: Helen Warren > Priority: Minor > Fix For: 3.1 > > Attachments: TestMultiSearchWildCard.java > > > We are searching across multiple indices using a MultiSearcher. There seems > to be a problem when we use a WildcardQuery to exclude documents from the > result set. I attach a set of unit tests illustrating the problem. > In these tests, we have two indices. Each index contains a set of documents > with fields for 'title', 'section' and 'index'. The final aim is to do a > keyword search, across both indices, on the title field and be able to > exclude documents from certain sections (and their subsections) using a > WildcardQuery on the section field. > > e.g. return documents from both indices which have the string 'xyzpqr' in > their title but which do not lie > in the news section or its subsections (section = /news/*). > > The first unit test (testExcludeSectionsWildCard) fails trying to do this. > If we relax any of the constraints made above, tests pass: > > * Don't use WildcardQuery, but pass in the news section and it's child > section to exclude explicitly (testExcludeSectionsExplicit)</li> > * Exclude results from just one section, not it's children too i.e. don't use > WildcardQuery(testExcludeSingleSection)</li> > * Do use WildcardQuery, and exclude a section and its children, but just use > one index thereby using the simple > IndexReader and IndexSearcher objects (testExcludeSectionsOneIndex). > * Try the boolean MUST clause rather than MUST_NOT using the WildcardQuery > i.e. only include results from the /news/ section > and its children. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
