Add an operator to edismax for word order
-----------------------------------------
Key: SOLR-3101
URL: https://issues.apache.org/jira/browse/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).
