Hi !

I am currently playing with facets, and I am facing the following problems.  
The documents I am indexing are products. They have different fields  
(Title, id) and a list of attributes, defined in a nested field.

My mapping looks like this :

mappings: {  
product: {  
properties: {  
title: {  
type: string  
}  
id: {  
type: long  
}  
attributes: {  
dynamic: true  
properties: {  
screen: {  
type: string  
}  
color: {  
type: string  
}  
brand: {  
type: string  
}  
type: {  
type: string  
}  
memory: {  
type: string  
}  
}  
}  
}  
}  
}

What I want to do, is to get a count of the different values I have within  
"attributes". I can easily do it by specyfing the name of theses fields in  
the facets by doing something like this :

{  
"query" : {  
"match\_all" : {}  
},  
"facets" : {  
"tags" : { "terms" : {"fields" : ["brand", "color"]} }  
}  
}

But what i would actually like to do is a bit different. As I may not know  
the fields within the "attributes" part, i would like to build my facets by  
doing something like "Give me a count for all the fields within the  
attribute field".  
Is this somehow possible ?

Thanks in advance

Sebastian

I would probably ask ES for mapping of your type. Then build one Terms facet per field in attributes object.

So you should probably handle that on client side.

Thanks for you answer, we decided to follow a similar approach !
