>                 Key: SOLR-507

>             Project: Solr
>          Issue Type: New Feature

> 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.
