D: good question, I think if F > tfn, then D > 0, but I guess I have to prove it (and
fix it if it isn't).

Could you tell me which sims were affected negatively?

freq: I didn't know about that! Still, I want to provide not "plausible", but at least "safe"
statistics in this case. You didn't touch docFreq and numberOfDocuments, so I assumed at least
these two are filled with the actual values, is that so?

> Write test cases to test the new Similarities added in [LUCENE-3220|https://issues.apache.org/jira/browse/LUCENE-3220].
Two types of test cases will be created:
>  * unit tests, in which mock statistics are provided to the Similarities and the score
is validated against hand calculations;
>  * integration tests, in which a small collection is indexed and then searched using
the Similarities.
> Performance tests will be performed in a separate issue.
