Subject [jira] [Commented] (SOLR-3100) Add an operator to edismax for term quorum
Date Tue, 07 Feb 2012 04:36:59 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13202070#comment-13202070
] 

Mike commented on SOLR-3100:
----------------------------

I'd suggest we follow the syntax of Sphinx[1], and require that this be used immediately after
(), with a slash and then a count. Pretty sure this doesn't conflict with anything we've already
got.

So queries would look essentially like this:
(a b c d)/2 e

> 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.
