Description

If the sort spec includes a sort field that needs scores, and if trackDocScores or trackMaxScore is set, then TopFieldCollectors may compute the score several times on the same document, once to check whether the hit is competitive, and once to update maxScore or to set the score on the ScoreDoc.
