[jira] [Created] (LUCENE-9393) FunctionScoreQuery shouldn’t use TOP_DOCS for creating inner weight

Tomas Eduardo Fernandez Lobbe created LUCENE-9393:
-----------------------------------------------------

             Summary: FunctionScoreQuery shouldn’t use TOP_DOCS for creating inner weight
                 Key: LUCENE-9393
                 URL: https://issues.apache.org/jira/browse/LUCENE-9393
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Tomas Eduardo Fernandez Lobbe


{{FunctionScoreQuery.createWeight}} creates the weight of the inner query using the {{scoreMode}} from it’s input parameter, however, FunctionScoreQuery can’t really use WAND algorithm, and the Scorer used will ignore calls to set competitive scores.  FunctionScoreQuery should just turn {{TOP_DOCS}} to {{COMPLETE}} before creating the inner query's weight.
