      Description

      SimpleNaiveBayesClassifier users term frequencies with add one smoothing to calculate likelihood and just tf for prior. Given Lucene has switched to BM25 it would be better to have a different impl which uses BM25
      scoring as a probability measure of both prior and likelihood.
