setTopLevelScoringClause

Inform this ScorerSupplier that its returned scorers produce scores that get passed to the collector, as opposed to partial scores that then need to get combined (e.g. summed up). Note that this method also gets called if scores are not requested, e.g. because the score mode is ScoreMode.COMPLETE_NO_SCORES, so implementations should look at both the score mode and this boolean to know whether to prepare for reacting to Scorer.setMinCompetitiveScore calls.
