    Issue Type: Sub-task  (was: New Feature)
        Parent: SOLR-3028

> 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).
