fuzzy matching / configurable distance function?

[Joe Calderon <ca...@gmail.com>]

is it possible to configure the distance formula used by fuzzy
matching? i see there are other under the function query page under
strdist but im wondering if they are applicable to fuzzy matching

thx much

Levenstein algo is currently hardcoded (FuzzyTermEnum class) in Lucene 2.9.1
and 3.0...
There are samples of other distance in "contrib" folder
If you want to play with distance, check
http://issues.apache.org/jira/browse/LUCENE-2230
It works if distance is integer and follows "metric space axioms":
D(a,b)=D(b,a)
D(a,b)+D(b,c)>=D(a,c)


Probably SOLR can provide more freedom with plugged-in distances...
