Chris Male commented on LUCENE-2507:
------------------------------------

That is a very good idea yes, but I don't think its necessary to do that before this is committed.
  We can do that afterwards, get an idea of where the spellcheckers are, and improve them
through other issues if needs be.

> The current spellchecker makes an n-gram index of your terms, and queries this for spellchecking.
> The terms that come back from the n-gram query are then re-ranked by an algorithm such
as Levenshtein.
> Alternatively, we could just do a levenshtein query directly against the index, then
we wouldn't need
> a separate index to rebuild.
