Adrien Grand commented on LUCENE-10574:
---------------------------------------
Correct: 3 docs at a time with a 50% constraint. I can change this 3 number,
I'm getting similar results.
These floors might indeed not be great, but I am nervous about removing them
completely. They've been here forever and I'm pretty sure that there are
important users who rely heavily on them. FWIW I did not make this 50% number
configurable on purpose to make it easier to move to a completely different
approach in the future if needed.
