-------------------------------------
Summary: ValueSource.asDoubleValues shouldn't fetch score
Key: LUCENE-10252
URL: https://issues.apache.org/jira/browse/LUCENE-10252
Project: Lucene - Core
Issue Type: Improvement
Components: modules/query
Reporter: David Smiley
The ValueSource.asDoubleValuesSource() method bridges the old API to the new
one. It's rather important because boosting a query no longer has an old API;
in its place is using this method and passing to
FunctionScoreQuery.boostByValue. Unfortunately, asDoubleValuesSource will
fetch/compute the score for the document in order to expose it in a Scorable on
the "scorer" key of the context Map. AFAICT nothing in Lucene or Solr actually
uses this. If it should be kept, the Scorable's score() method could fetch it
at that time (e.g. on-demand).
