             Summary: Expose some IndexReader stats via DoubleValuesSources
                 Key: LUCENE-7736
                 URL: https://issues.apache.org/jira/browse/LUCENE-7736
             Project: Lucene - Core
          Issue Type: New Feature
            Reporter: Alan Woodward
            Assignee: Alan Woodward
            Priority: Minor


We have a number of ValueSource implementations that expose IndexReader stats (numDocs, termFreq, etc).  We should re-implement these as DoubleValuesSources, allowing them to be used in FunctionScoreQuery, etc.
