I have an index with the following fields: user-ids : multivalued field timestamp : date field "user": [ "w@c.com", "d@s.edu", "a@s.org" ], "timestamp": 967568760000 Each document represents one login attempt at the given timestamp by the list of users, and each user appears only once in the user list. I want to write a query to get how many logins did each user attempt each day. I am trying to use date\_histogram but cannot figure out how to pivot it on user. ---

I don't think you can in core ES, you'd want to split those into individual records. Otherwise, something like graph might be able to do it. ---
