Unfortunately, my "use case" is a customer who wants stemming, but has very little knowledge of what that means except they think they want it.
I agree with your last comment. So, here's my contribution: Original porter kstem minStem ------- ------- ------- ------- country countri country country run run run run runs run runs run running run running running read read read read reading read reading reading reader reader reader reader association associ association association associate associ associate associate listing list list listing water water water water watered water water watered sure sure sure sure surely sure surely surely fred's fred' fred's fred' roses rose rose rose Still not sure which one to pick. Porter is more aggressive. Min stemmer is pretty minimal. Perhaps the kstemmer is "just right" :-) Cheers Scott -----Original Message----- From: Jack Krupansky [mailto:j...@basetechnology.com] Sent: Wednesday, November 14, 2012 4:14 PM To: java-user@lucene.apache.org Subject: Re: Which stemmer? What is your use case? If you don't have a specific use case in mind, try each of them with some common words that you expect will or won't be stemmed. If you have Solr, you can experiment interactively using the Solr Admin Analysis web page. It would be nice if the javadoc for each stemmer gave a handful of examples that illustrated how some common words are stemmed. -- Jack Krupansky -----Original Message----- From: Scott Smith Sent: Wednesday, November 14, 2012 10:55 AM To: java-user@lucene.apache.org Subject: Which stemmer? Does anyone have any experience with the stemmers? I know that Porter is what "everyone" uses. Am I better off with KStemFilter (better performance) or ?? Does anyone understand the differences between the various stemmers and how to choose one over another? --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
