Subject [jira] [Commented] (SOLR-3100) Add an operator to edismax for term quorum
Date Wed, 08 Feb 2012 06:30:59 GMT


Mike commented on SOLR-3100:

I don't know. We have the MM parameter, but not an operator. I don't know where Lucene's query
parser ends and where edismax begins. Happy to change this to a Lucene issue if that makes
sense though.

Anybody know definitively where this should go?

> A project I'm working on requires *term quorum* searching with stemming turned off. The
users are accostomed to Sphinx search, and thus expect a query like [ A AND (B C D)/2 ] to
return only documents that contain A or at least two of B, C or D. 
> So this document would match:
> a b c
> But this one wouldn't:
> a b
> This can be a useful form of fuzzy searching, and I think we support it via the MM parameter,
but we lack a user-facing operator for this. It would be great to add it.
