> Currently getting the values of a feature in a feature field requires another
> numeric field to be indexed containing the values. It would be useful to be
> able to obtain the indexed values of features from the feature field directly
> using a `DoubleValues` implementation.
> The feature sort implemented in
> https://issues.apache.org/jira/browse/LUCENE-8803 could also be moved to
> using this `DoubleValue` implementation to avoid duplicating logic.
