> Feature vector shingles currently contain three decimal places, e.g. _[0.101, 0.202, 0.303]_.
> Since min hash is not aware of the fact that second and third decimal place values are less important than first place values, it is likely that this will impact the search precision.
> We should be truncating to the first decimal place.
