The polish stemmer jar file needs to be findable by Solr, if you copy it to <solr_home>/lib and restart solr you should be set.
Alternatively, you can add another <lib> directive to the solrconfig.xml file (there are several examples in that file already). I'm a little confused about not being able to find TokenFilter, is that still a problem? HTH Erick On Tue, Nov 2, 2010 at 8:07 AM, Jakub Godawa <jakub.god...@gmail.com> wrote: > Thank you Bernd!
