Any field that’s unique per doc would do, but yeah, that’s usually an ID.
Hmmm, I don’t see why separate queries for 0-f are necessary if you’re firing at individual replicas. Each replica should have multiple UUIDs that start with 0-f. Unless I misunderstand and you’re just firing off, say, 16 threads at the entire collection rather than individual shards which would work too. But for individual shards I think you need to look for all possible IDs...
