ASF subversion and git services commented on SOLR-2649: ------------------------------------------------------- Commit 38714399760889d2d7b188a87341aade6139ffef in lucene-solr's branch refs/heads/master from [~steve_rowe] [ https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=3871439 ] SOLR-8812: edismax: turn off mm processing if no explicit mm spec is provided and there are explicit operators (except for AND) - addresses problems caused by SOLR-2649 > MM ignored in edismax queries with operators > -------------------------------------------- > > Key: SOLR-2649 > URL: https://issues.apache.org/jira/browse/SOLR-2649 > Project: Solr > Issue Type: Improvement > Components: query parsers > Reporter: Magnus Bergmark > Assignee: Erick Erickson > Fix For: 5.5, 6.0 > > Attachments: SOLR-2649-with-Qop.patch, SOLR-2649-with-Qop.patch, > SOLR-2649.diff, SOLR-2649.patch, SOLR-2649.patch > > > Hypothetical scenario: > 1. User searches for "stocks oil gold" with MM set to "50%" > 2. User adds "-stockings" to the query: "stocks oil gold -stockings" > 3. User gets no hits since MM was ignored and all terms where AND-ed > together > The behavior seems to be intentional, although the reason why is never > explained: > // For correct lucene queries, turn off mm processing if there > // were explicit operators (except for AND). > boolean doMinMatched = (numOR + numNOT + numPluses + numMinuses) == 0; > (lines 232-234 taken from > tags/lucene_solr_3_3/solr/src/java/org/apache/solr/search/ExtendedDismaxQParserPlugin.java) > This makes edismax unsuitable as an replacement to dismax; mm is one of the > primary features of dismax. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
