First off: you have to be more specific about what you mean when you say neither ... or ... works" .. what happens? Do you get an error on startup? what does the error look like?
You also have to be clear about which version of Solr you are using ... GermanStemFilterFactory was added after Solr 1.2. : I wonder how I can setup a German stemmer correctly in a list of filters for a : field type definition. : : Neither : : <filter class="solr.GermanStemFilterFactory"/> : : nor : : <filter class="org.apache.solr.analysis.GermanStemFilterFactory"/> : : works. Any suggestions? -Hoss
