Zach Chen commented on LUCENE-10480:
------------------------------------
Ok I see. Maybe I can also try to run some benchmark experiments with different
JVM compilation / code cache parameters to further test things out. Will report
back if I find something interesting!

> WANDScorer is nice, but it also has lots of overhead to maintain its
> invariants: one linked list for the current candidates, one priority queue of
> scorers that are behind, another one for scorers that are ahead. All this
> could be simplified in the 2-clauses case, which feels worth specializing for
> as it's very common that end users enter queries that only have two terms?
