Subject [jira] Updated: (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:all-tabpanel
]

Preetam Rao updated SOLR-1384:
------------------------------

          Description: 
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:
