Minimum Should Match

[Grant Ingersoll]

Is there a default "mm" value (minimum should match) for the  
DisMaxReqHandler?  I have two optional clauses and I have not declared  
any mm value in my config and I am not getting results, despite  
knowing that both clauses return results individually.  In debugging,  
Solr, is definitely returning "2" for the min should match?  Is this a  
bug, or an undocumented feature?  That is, should I file a JIRA issue,  
or update the Wiki?

Thanks,
Grant
