What would it take to do something like the following for Solr?

> 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.
