MatchAllDocsQuery, MultiSearcher and a custom HitCollector throwing exception -----------------------------------------------------------------------------
Key: LUCENE-556 URL: http://issues.apache.org/jira/browse/LUCENE-556 Project: Lucene - Java Type: Bug Components: Search Versions: 1.9 Environment: xp sp2, jdk1.5 Reporter: jm Priority: Minor I have encountered an issue with lucene1.9.1. It involves MatchAllDocsQuery, MultiSearcher and a custom HitCollector. The following code throws java.lang.UnsupportedOperationException. If I remove the MatchAllDocsQuery condition (comment whole //1 block), or if I dont use the custom hitcollector (ms.search(mbq); instead of ms.search(mbq, allcoll);) the exception goes away. By stepping into the source I can see it seems due to MatchAllDocsQuery no implementing extractTerms().... Searcher searcher = new IndexSearcher("c:\\projects\\mig\\runtime\\index\\01Aug16\\"); Searchable[] indexes = new IndexSearcher[1]; indexes[0] = searcher; MultiSearcher ms = new MultiSearcher(indexes); AllCollector allcoll = new AllCollector(ms); BooleanQuery mbq = new BooleanQuery(); mbq.add(new TermQuery(new Term("body", "value1")), BooleanClause.Occur.MUST_NOT); // 1 MatchAllDocsQuery alld = new MatchAllDocsQuery(); mbq.add(alld, BooleanClause.Occur.MUST); // System.out.println("Query: " + mbq.toString()); // 2 ms.search(mbq, allcoll); //ms.search(mbq); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
