I was looking at the Russian Stem Filter Factory which is present in src\java\org\apache\solr\analysis\ I found that it uses org.apache.lucene.analysis.TokenStream and org.apache.lucene.analysis.ru.RussianStemFilter. I also found that these classes are present in the lucene-analyzers-3.0.3.jar file present in contrib/analyzers/common folders. Where exactly do I need to place this jar file to be able to use the RussianStemmer. I am a newbie, please help? -- View this message in context: http://lucene.472066.n3.nabble.com/Stemmers-tp2143442p2143442.html Sent from the Lucene - General mailing list archive at Nabble.com.
