The explanation ` skip low-scoring matches` is great, I looked up some docs
and inspect some related code.
I noticed the ` block-max WAND` mode only work when ScoreMode.TOP_SCORES is

I'm not au courant with highlighters as I used to be. I think some of them

To clarify, the scoring process is not accelerated because we
terminate early but because we can skip low-scoring matches (there
might be competitive hits at the very end of the index).
CompetitiveImpactAccumulator is indeed related to WAND. It helps store
the maximum score impacts per block of do
Hi,
We discuss some topic from https://github.com/apache/lucene-solr/pull/595. As
Atri Sharma propose discuss with the java dev list.

In impact mode, `CompetitiveImpactAccumulator` will record
