Sort.needsScores介绍

[英]Returns true if the relevance score is needed to sort documents.
[中]如果排序文档需要相关性分数，则返回true。

public SimpleFieldCollector(Sort sort, FieldValueHitQueue<Entry> queue, int numHits, boolean fillFields,
  boolean trackDocScores, boolean trackMaxScore, boolean trackTotalHits) {

 }

 this.trackMaxScore = trackMaxScore;
 // If one of the sort fields needs scores, and if we also track scores, then
 // we might call scorer.score() several times per doc so wrapping the scorer
 // to cache scores would help
