Review Comment:
I do see the reason for the failure now, the custom query this test relies
on makes assumptions about the scorer supplier being called once per
LeafReaderContext. That would be addressed by removing work duplication across
partitions of the same segment. Otherwise we do segment level work once per
partition, instead of doing it once and sharing the result. Also, depending on
the implementation, we may also multiply results in that we would go over the
same segment multiple times.
