Hi, I’m developing a multi language Solr index, where I have a single core for each one. I use SnowballPorterFilterFactory for German, French and Italian languages with excellent results.
My problem appears when I try to create a Polish stemmed index. There isn’t a Snowball implementation for Polish, but I found a lucene one: http://www.getopt.org/stempel/index.html#distrib I included the jar into Solr lib folder and included the filter into the appropriate fieldtype (<filter class="org.getopt.stempel.lucene.StempelFilter" />) but when I run the server this error appears: GRAVE: *org.apache.solr.common.SolrException*: Error instantiating class: 'org.getopt.stempel.lucene.StempelFilter' Has anybody found this error before? Other solutions for Polish Stemming would be great too. Thanks in advance.
