We had similar problems and then switched to KStem and have been pretty happy with the results.

Is there an option to perform less aggressive stemming in solr? We're using the Porter stemmer. I see that there is an option for Snowball, but my understanding is that Snowball is a refinement of Porter rather than something radically different. I think we'd be best off with something very basic, possibly as simple as removing plural endings. Our index is over product descriptions, so it's important that we stem normal variations in nouns, but adverbs, verbs and possibly adjective variations are not so important and sometimes cause problems for us.
