> {{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.
