Then I missed the point. You are saying that, for example:
We query Reg A, federated with Reg B and Reg C.
- Query matches 4 objects in Reg A
- Query matches 5 objects in Reg B
- Query matches 3 objects in Reg C, 2 of wich are replicas from A.
totalResultCount = ?
I though MAX would return "5" in this case.
Plain SUM would be "12", but that is incorrect too.
Best answer would be "10"
