The group command was deprecated in version 3.4. We are not planning on implementing further improvements to this command. Closing this ticket as Won't Fix.

ah, that's really multi value keys

Let's imagine the following data structure in a collection:

{ "emailMessageId" : "<12...@example.com>", "emailAddresses" : [

{ "email" : "us...@example.com", "type" : "from" }

,

{ "email" : "us...@example.com", "type" : "to" }

] }
{ "emailMessageId" : "<12...@example.com>", "emailAddresses" : [

{ "email" : "us...@example.com", "type" : "from" }

,

{ "email" : "us...@example.com", "type" : "to" }

] }

It would be nice to be able to do a group call for the key emailAddresses.email

Can you submit an example of what you mean?
