> ElasticSearch use CancellableBulkScorer to fast cancel long time query
> execution by dividing one segment docs to many small split docs. For every
> split docs, collector.setScorer(scorer) is called, then
> NumericLeafComparator#setScorer is called. As a result, for one segment,
> NumericLeafComparator#setScorer is called many times.
> Every time NumericLeafComparator#setScorer is called, the
> NumericLeafComparator#iteratorCost is reset to the Scorer.cost and increase
> many unnecessary pointValues#intersect calls to get competitive docs.
