    I expected them to be API compatible. Not that it matters to me but I had looked to see.

      This is a good point and was a difficult design decision. The reasons for changing the API are:

      - easier to use with untokenized corpus and questions

      - to fix issues with the tokenizing ( e.g. https://github.com/dorianbrown/rank_bm25/issues/38 ); also rank_bm25 provides no default tokenizer, a naive split-on-whitespace is a wrong choice

      - considerably simplify the code (way less SLOC)

      - point out the similarities of the algorithms for educational purpuses / further development

      In practice, the differences are minimal ( see Example 3: comparison with rank_bm25 ).
