[jira] [Created] (LUCENE-7721) Make it easier to combine scores with index-time factors

Adrien Grand created LUCENE-7721:
------------------------------------

             Summary: Make it easier to combine scores with index-time factors
                 Key: LUCENE-7721
                 URL: https://issues.apache.org/jira/browse/LUCENE-7721
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Adrien Grand
            Priority: Minor


With the removal of index-time boosts, we should make it easy to combine the score with index-time factors stored in a doc-values field. We already have BoostedQuery that does it but it uses the old values source API and forcefully multiplies the value of the function with the score.

I think we should move it to core, improve it and make it work with the new values source API, hopefully in a way that makes integrating expressions easy?
