You haven't answered _why_ this is a good idea. I'm having a hard
time understanding what would be _useful_ about sorting this way. Just
because the sum of scores in a group is greater than the sum of scores
in another says _nothing_ about how relevant any of the docs in the group
are relative to each other.
I mean group 1 could have 10M documents all with a score of .01 and group
2 could have 1 document with a score of 1,000 and group 1 would sort
first.
So unless you have some unusual use-case which you haven't yet articulated,
this seems like a bad idea.
Best,
Erick
