本文整理了Java中org.apache.lucene.search.Sort.needsScores()方法的一些代码示例，展示了Sort.needsScores()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Sort.needsScores()方法的具体详情如下：
包路径：org.apache.lucene.search.Sort
类名称：Sort
方法名：needsScores

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。

代码示例

代码示例来源：origin: org.apache.lucene/lucene-core

  1. public SimpleFieldCollector(Sort sort, FieldValueHitQueue<Entry> queue, int numHits, boolean fillFields,
  2.   boolean trackDocScores, boolean trackMaxScore, boolean trackTotalHits) {
  3.  super(queue, numHits, fillFields, sort.needsScores() || trackDocScores || trackMaxScore);
  4.  this.sort = sort;
  5.  this.queue = queue;
  6.  if (trackMaxScore) {
  7.   maxScore = Float.NEGATIVE_INFINITY; // otherwise we would keep NaN
  8.  }
  9.  this.trackDocScores = trackDocScores;
  10.  this.trackMaxScore = trackMaxScore;
  11.  // If one of the sort fields needs scores, and if we also track scores, then
  12.  // we might call scorer.score() several times per doc so wrapping the scorer
  13.  // to cache scores would help
  14.  this.mayNeedScoresTwice = sort.needsScores() && (trackDocScores || trackMaxScore);
  15.  this.trackTotalHits = trackTotalHits;
  16. }

  7. }

  14.  }
  15.  FieldComparator<?>[] comparators = queue.comparators;

  18.   @SuppressWarnings("unchecked")
  19.   FieldComparator<Object> comparator = (FieldComparator<Object>) comparators[i];
  20.   comparator.setTopValue(after.fields[i]);
