> We currently encode taxonomy ordinals using varint style packing in a binary
> doc values field. I suspect there have been a number of improvements to
> SortedNumericDocValues since taxonomy faceting was first introduced, and I
> plan to explore replacing the custom binary format we have today with a
> SORTED_NUMERIC type dv field instead.
> I'll report benchmark results and index size impact here.
