What function in saved search works like a group by and still allows you to use another summary type such as max/min?

Can you provide some more context on what you are trying to do.

I am trying to aggregate by child of a parent and get the minimum of the two child. I only need 1 row for the parent in the search. It's like min(sum({amount} group by child). I don't know what functions can do that. @raghav
