> factor out a shared spellchecking module
> ----------------------------------------
>
> Key: LUCENE-2995
> URL: https://issues.apache.org/jira/browse/LUCENE-2995
> Project: Lucene - Java
> Issue Type: Task
> Reporter: Robert Muir
> Fix For: 4.0
>
> Attachments: LUCENE-2995.patch, LUCENE-2995.patch
>
>
> In lucene's contrib we have spellchecking support (index-based spellchecker,
> directspellchecker, etc).
> we also have some things like pluggable comparators.
> In solr we have auto-suggest support (with two implementations it looks
> like), some good utilities like HighFrequencyDictionary, etc.
> I think spellchecking is really important... google has upped the ante to
> what users expect.
> So I propose we combine all this stuff into a shared modules/spellchecker,
> which will make it easier
> to refactor and improve the quality.
