[jira] [Updated] (SOLR-2649) MM ignored in edismax queries with
operators
[ https://issues.apache.org/jira/browse/SOLR-2649?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jan Høydahl updated SOLR-2649:
------------------------------
Affects Version/s: (was: 3.3)
Fix Version/s: 4.0
> MM ignored in edismax queries with operators
> --------------------------------------------
>
> Key: SOLR-2649
> URL: https://issues.apache.org/jira/browse/SOLR-2649
> Project: Solr
> Issue Type: Bug
> Components: query parsers
> Reporter: Magnus Bergmark
> Priority: Minor
> Fix For: 4.0
>
>
> 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.
