Subject [jira] Commented: (SOLR-1384) Allow fq or q to specify boolean query min must match like dismax's mm parameter
Date Wed, 26 Aug 2009 06:52:59 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12747802#action_12747802

Noble Paul commented on SOLR-1384:
----------------------------------

why should this be limited to 'fq' ? isn't it valid for 'q' as well ?

> Dis max query provides "mm" parameter that can be set on the underlying Lucene Boolean
OR query using setMinimumNumberShouldMatch()  method.
> It will be great if we can have the same support on any fq or q that specifies more than
one term. This means we don't need to switch to dis max query just for this one use case.
> Example might look like this:
> fq={!minMustMatch=75%}street:"917 Z st NW Washington DC"
> Full supported syntax for the value allowed should be this:
> http://lucene.apache.org/solr/api/org/apache/solr/util/doc-files/min-should-match.html
> This is the underlying lucene facility:
> http://www.netlikon.de/docs/javadoc-lucene/lucene_1_9/org/apache/lucene/search/BooleanQuery.html#setMinimumNumberShouldMatch%28int%29
