> Somehow related to LUCENE-7407, after the transition, the uninvert time of numeric fields
has gone up substantially.  I haven't tested all field types yet, just integer fields, which
show a 55% performance regression for the initial uninvert time.
> This was tested with a numeric field of cardinality 1M on a 10M doc index.

> q=id:1&sort=my_numeric_field desc
