[jira] [Created] (LUCENE-8490) Separate scoring features from
Queries
Alan Woodward created LUCENE-8490:
-------------------------------------
Summary: 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
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.
