MultiTermQueryWrapperFilter<http://lucene.apache.org/java/2_9_1/api/all/org/apache/lucene/search/MultiTermQueryWrapperFilter.html#MultiTermQueryWrapperFilter(org.apache.lucene.search.MultiTermQuery)>(MultiTermQuery<http://lucene.apache.org/java/2_9_1/api/all/org/apache/lucene/search/MultiTermQuery.html>
query)


I guess I can write a class that extends MultiTermQueryWrapperFilter.  Is this the intended
usage?

Automaton is only in Lucene/Solr Trunk. To get a filter out of FuzzyQuery, use MultiTermQueryWrapperFilter(new
FuzzyQuery(...))

Subject: LevenshteinFilter proposal

Hi Folks,

I'm very interested in using (or developing!) a Levenshtein Filter within the family of Solr
Filter objects. I don't see such a class today anywhere. I see how the AutomatonQuery object
would permit such a thing to be built, but to date I don't know of anyone who has built one.
Do you?  If not, I'm willing to give it a whirl.  Also, AutomatonQuery doesn't seem to come
up when I look for it in the javadocs for Lucene - can you point me in the correct direction?
Thanks!
Karl
