automaton spellchecker
----------------------

                 Key: LUCENE-2507
                 URL: https://issues.apache.org/jira/browse/LUCENE-2507
             Project: Lucene - Java
          Issue Type: New Feature
          Components: contrib/spellchecker
            Reporter: Robert Muir
             Fix For: 4.0


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.
