Jan Høydahl updated SOLR-3099:
------------------------------
Fix Version/s: 4.0
Remaining Estimate: (was: 4h)
Original Estimate: (was: 4h)
This is wanted. Scheduling for 4.x. I think for this to work we need some
better metadata support in analysis? Currently you can tag a token with a
TOKENTYPE, so the stemmer could add the stemmed token on same position with
tokentype=stem. However, we'd need a way to convey from the query that [=foo]
should NOT match the "stem" token types?
Also, could we not simply adopt Google's syntax, i.e. if a single token is
quoted, it is searched verbatim, e.g. foo "bar".

> 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).
