Add query operator, index structure, and analyzer for "exact match" searching
-----------------------------------------------------------------------------
Key: SOLR-3099
URL: https://issues.apache.org/jira/browse/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).
