----------------------------------
Attachment: LUCENE-8490.patch
> Separate scoring features from Queries
> --------------------------------------

> Key: LUCENE-8490
> URL: https://issues.apache.org/jira/browse/LUCENE-8490
> Project: Lucene - Core
> Issue Type: New Feature
> Reporter: Alan Woodward
> Assignee: Alan Woodward
> Priority: Major
> Attachments: LUCENE-8490.patch

>
> We currently have two types of 'purely scoring' queries, produced by static
> methods on FeatureField and more recently on LongPoint (for distance or
> recency boosting). These don't really make sense as standalone queries, and
> are designed to be used as supplementary SHOULD clauses in boolean queries.
> I think these would be easier to use (and would prevent misuses, such as
> using them in FILTER or MUST clauses) if we designated them as Features
> instead, with a separate class hierarchy, and add a specific feature() method
> to BooleanQuery.Builder.
