[jira] [Resolved] (LUCENE-7721) Make it easier to combine scores
with index-time factors
[ https://issues.apache.org/jira/browse/LUCENE-7721?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Adrien Grand resolved LUCENE-7721.
----------------------------------
Resolution: Implemented
I missed FunctionScoreQuery which already does this!

> Project: Lucene - Core

> 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?
