bulkScorer

Helper method that delegates to .scorerSupplier. It is implemented as

ScorerSupplier scorerSupplier = scorerSupplier(context);
if (scorerSupplier == null) {
// No docs match
return null;
}

scorerSupplier.setTopLevelScoringClause();
return scorerSupplier.bulkScorer();

A bulk scorer for the same LeafReaderContext instance may be requested multiple times as part of a single search call.
