Subject [jira] [Created] (SOLR-3101) Add an operator to edismax for word order
Date Mon, 06 Feb 2012 02:43:59 GMT
Add an operator to edismax for word order

                 Key: SOLR-3101
             Project: Solr
          Issue Type: New Feature
          Components: search
            Reporter: Mike

A project I'm working on requires *word order* searching. The users are accustomed to Sphinx
search, and expect a query like [ A << B ] to return only documents that contain the
term A before the term B.

I believe this can currently be done with the surround parser (SOLR-2703), but we lack an
operator for it. It would be great to add it, so that word order searches can be combined
by users into sophisticated queries. 

Note that this should also support a query like [ A << A], which would require that
the term be in the document twice (the first instance before the second).

This issue is part of a meta issue, SOLR-3028, that is requesting two other operators in edismax
(quorum search and exact match).
