How do you get nested facets with Searchkick/ElasticSearch

How can you do nested facets in ElastiSearch with the Searchkick gem?

I would like to achieve something like this:

  • Category Name
    • median price
    • count
    • min price
    • max price


Searchkick only support term facets, for median price you need stats facets

I suggest you to check elasticsearch-rails or elasticsearch-ruby project. I used to research all elasticsearch related gem, because of elasticsearch syntax is complex, no gem can provide such flexiable DSL. So I like write my own elasticsearch query
