Hello.  
I have structure like this  
`POST /cars/test/_bulk { "index": {}} { "name": "record1", "category_id" : 1, "category_name" : "CCC"} { "index": {}} { "name": "record2", "category_id" : 2, "category_name" : "AAA"} { "index": {}} { "name": "record3", "category_id" : 3, "category_name" : "BBB"} { "index": {}} { "name": "record4", "category_id" : 2, "category_name" : "AAA"}`

As you see I have a pairs: category\_id + category\_name  
I want to get array of unique pairs category\_id + category\_name.  
I have found that I can do it using aggregations.  
And it's work  
`GET /cars/transactions/_search { "size": 0, "aggs": { "group_by_id": { "terms": { "field": "category_id" }, "aggs": { "group_by_name": { "terms": { "field": "category_name" } } } } } }`

But what should I do to sort my result by category\_name?  
I tried to do something like this  
`"group_by_id": { "terms": { "field": "category_id", "order" : { "group_by_name.category_name": "asc" } }, ...`  
but it's not working.

Thank you
