Robert Muir commented on LUCENE-3888:
-------------------------------------

Thanks for the feedback Koji.

I'm not happy with the situation: I thought it would be easy to support
some rough Japanese spellcheck in 3.6 

But it just seems like we need to do a lot of cleanup to make it work,
I would rather fix all of these APIs and do it right the first time so
that things like distributed support work too.

> The "did you mean?" feature by using Lucene's spell checker cannot work well for Japanese
environment unfortunately and is the longstanding problem, because the logic needs comparatively
long text to check spells, but for some languages (e.g. Japanese), most words are too short
to use the spell checker.
> I think, for at least Japanese, the things can be improved if we split off the spell
check word and surface form in the spell check dictionary. Then we can use ReadingAttribute
for spell checking but CharTermAttribute for suggesting, for example.
