--------------------------------------
OK, those looked like easy wins to me but I get your point about better tests.

> I noticed two things we could do to improve the accuracy of our scores:
> - use {{Math.log1p(x)}} instead of {{Math.log(1+x)}}, especially when x is
> expected to be small
> - use doubles for intermediate values that are used to compute norms in
> BM25Similarity
