Hey community - does anyone have any experience or advice for working with dictionary-esque structures as facets? I have this case where I would like to filter on sizes (the values) based on an store id (the key):

[

{

"id": 1,

"name": "t-shirt",

"instockinstores" :  [

{ "123" : [36,37,38,39] },

{ "456" : [38,39,40,41] }

]

}

]

The problem is that I don't know the store ids beforehand. Is it possible to do something like this?
