Check cosine distance metric with dot product #4

The naming using cosine but it is probably implementing dot product instead. We should check the naming and update accordingly.

The naming is correct, the cosine distance is defined as 1 - dot(x,y) assuming the vectors are normalised. We might enable the dot product distance in the future although it is not really metric.
