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. |

Let's imagine the following data structure in a collection: { "emailMessageId" : "<12...@example.com>", "emailAddresses" : [ , { "email" : "us...@example.com", "type" : "to" }] } , { "email" : "us...@example.com", "type" : "to" }] } It would be nice to be able to do a group call for the key emailAddresses.email |
