Hi
Is anyone aware of subclasses of the Similarity class in Lucene? Two subclasses are: DefaultSimilarity and SimilarityDelegator . Are any other implemented subclasses of Similarity, developed by anyone else available on the web? For example, Language Model based similarity, or Okapi-BM similarity or different TFIDF weighing scehemes for similarity. If so, can you point me to them?
