### Description It's a spin off from #12204 #12245. I'm not sure it's really necessary, please advise. Now `ToParentBlockJoinQuery.BlockJoinScorer#explain` requests expensive `explain()` for every matching child doc. Here are possible measures: 1. extract BlockJoinScorer.setScoreAndFreq().freq to a field. Are we ready to afford this cost? 2. call score() in the beginning of explain(), use returned score to find child doc (for Min,Max modes) 3. request explain() only for the child found at 2. 4. use freq from 1. to output number of matches WDYD? -- This is an automated message from the Apache Git Service.
