Adrien Grand commented on LUCENE-10480:
---------------------------------------

Looking at this new scorer from the perspective of disjunctions within 
conjunctions, maybe there are bits from advance() that we could move to 
matches() so that we would hand it over to the other clause before we start 
doing expensive operations like computing scores. What do you think 
[~zacharymorn]?

> 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?
