[jira] [Created] (LUCENE-7720) Remove TFIDFSimilarity

Adrien Grand created LUCENE-7720:
------------------------------------

             Summary: Remove TFIDFSimilarity
                 Key: LUCENE-7720
                 URL: https://issues.apache.org/jira/browse/LUCENE-7720
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Adrien Grand
            Priority: Minor


It was already considered worse than BM25 and the removal of coords made it even worse, maybe we should think about removing it entirely? Backward compatibility should be easy since the BM25 similarity uses the same index-time encoding.
