Correct - it's not stemmed. If it were stemmed, there would be multiple cases where that wouldn't work either. For example, with the porter stemmer, "any"->"ani" and "anywhere"->"anywher" So if you had a document with "anywhere", a prefix query of "any*" wouldn't work if you stemmed it, and would match other things like "animal". -Yonik http://www.lucidimagination.com
