Hoss Man updated LUCENE-3833:
-----------------------------
Summary: Add an operator to query parser for term quorum (ie:
BooleanQuery.setMinimumNumberShouldMatch) (was: Add an operator to edismax for
term quorum)
Moved issue from Solr to Lucene since it should really be dealt with in the
underlying query parser(s).
I would suggest that the "~" syntax makes more sense then "/" for this (ie: {{
A AND (B C D)~2}} since...
* "/" was recently added to the query parser as a metacharacter for "quoting"
regex queries and the extremely different meanings might confuse people
* "~" already serves nearly the same purpose for phrases (slop) and fuzzy
queries (amount of fuzziness) ... it seems a natural way to express "how many"
of the clauses you want to match.

> Key: LUCENE-3833
> URL: https://issues.apache.org/jira/browse/LUCENE-3833
> Project: Lucene - Java
> Issue Type: New Feature
> Components: core/queryparser
> Reporter: Mike
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> 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.
