[jira] [Created] (LUCENE-8815) Enable retrieving of feature values through a DoubleValues implementation

Colin Goodheart-Smithe created LUCENE-8815:
----------------------------------------------

             Summary: Enable retrieving of feature values through a DoubleValues implementation
                 Key: LUCENE-8815
                 URL: https://issues.apache.org/jira/browse/LUCENE-8815
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Colin Goodheart-Smithe


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.
