Product attribute aggregation with Elasticsearch?

Question

EAV

Friends, hello!
Having a similar problem as here:
stackoverflow.com/questions/23627105/how-to-aggreg...
I have an EAV model in the database. I'm doing data mapping on Elasticsearch. My situation is the same as in the above example.
The data is taken from the example above.

POST myindex/product/1
{
    "name": "Shirt 1",
    "manufacturer": "Adidas",
    "options":[
            {
                "id": 1,
                "name": "color",
                "values" : [
                        {
                            "id": 1,
                            "name": "blue"
                        }    ,
                        {
                            "id": 2,
                            "name": "green"
                        }   
                    ]
            },
            {
                "id": 2,
                "name": "Size",
                "values" : [
                        {
                            "id": 5,
                            "name": "M"
                        }    
                    ]
            }
        ],
    "price":100
}

- color (3)
-- blue (1
-- green (2)
-size (4)
-- M (2)
-- L (1)
-- XL (3
