------------------------------------
A related item from Lucene project...
* LUCENE-626 "Extended spell checker with phrase support and adaptive user
session analysis" provides phrase-level spell suggestions.
> Spell Checking Improvements
> ---------------------------
>
> Key: SOLR-507
> URL: https://issues.apache.org/jira/browse/SOLR-507
> Project: Solr
> Issue Type: New Feature
> Components: spellchecker
> Reporter: Jayson Minard
>
> Creating a placeholder issue to track Spell Checking Improvements.
> Individual issues can later be created and linked for each area of separable
> concern when they are determined.
> Areas to discuss include:
> # spell suggestions from within the current query (minus terms being
> corrected) and filter so that suggestions are always valid
> ** need approaches to merging the spelling list with the current mask of
> valid records. Also, is this a better change to Lucene first, or something
> that belongs in Solr?
> ** need to add spell checking as query component and make available to
> various query handlers
> ** spell checking to be field specific to support responding correctly with
> dismax queries
> # spell suggestions from a distributed search (SOLR-303)
> # spell suggestions as a search component to augment other queries
> What are other typical areas of concern, or suggestions for improvements for
> spell checking that can be tracked?
> I am willing to look at driving a patch for this area, especially for spell
> checking working within the current result set, and across distributed
> search.
