I see KStem being mentioned lately. It's been 5+ years since I looked at the original KStem stuff, but I recall there being a license issue with the *original* KStem. I think it was under some flavour of GPL and that was the reason why we didn't include it in Lucene/Solr back then. I say this now because I saw people said KStem was released under BSD license, which doesn't match what I saw 5+ years ago.
