then this will sort the documents in descending score order. The scores will be
positive. If you want to sort in ascending order, then use the following code:
a new RescoringMatchScorer.Builder. Set the parameters for scorer
on the Builder, and use the Builder#build() method
to create a concrete instance of RescoringMatchScorer
