Subject [jira] [Created] (SOLR-3099) Add query operator, index structure, and analyzer for "exact match" searching

Add query operator, index structure, and analyzer for "exact match" searching

                 Key: SOLR-3099
             Project: Solr
          Issue Type: New Feature
          Components: Schema and Analysis
            Reporter: Mike

A project I'm working on requires *exact match* searching with stemming turned off. The users
are accostomed to Sphinx search, and thus expect a query like [ =runs ] to return only documents
that contain the exact term, "runs", and not the stemmed word "run".

In SOLR-2866, there is similar work, but I believe it is different because it uses a huge-synonym
file rather than storing the original terms directly in the index. 

What I'd like instead is two things:
1. An analyzer that says, "store the original form of all words in the index along with the
stemmed variations." If necessary, it's fine if this is simply an unstemmed field, but that
seems cumbersome schema-wise and performance-wise.
2. An operator in edismax that allows users to query the exact form of the word. Sphinx uses
the equals sign (=), and that makes sense logically to me.

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