[jira] [Commented] (LUCENE-8340) Allow to boost by recency

    [ https://issues.apache.org/jira/browse/LUCENE-8340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16579796#comment-16579796 ] 

Adrien Grand commented on LUCENE-8340:
--------------------------------------

bq. we need to do some changes to make boolean queries as well in order to propagate setMinCompetitiveScore calls to their sub clauses

It turns out that [~jim.ferenczi] is implementing this in LUCENE-8448 for other reasons.

> I would like that we support something like \{{FeatureField.newSaturationQuery}} but that works with features that are computed dynamically like recency or geo-distance, and is still optimized for top-hits collection. I'm starting with recency because it makes things a bit easier even though I suspect that geo-distance might be a more common need.
