Description

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).
