Nested documents & faceting

Elastic Stack Elasticsearch

You need to use nested mapping in this case for item. Explained here:

When faceting, you can facet on nested objects, check here:

I have a product "Cotton Dress" and 2 items for that product:
{"size" : "S", "color" : "black"}, {"size" : "M", "color" : "blue"}

  1. How do I represent them as a JSON that I can index, is it something
    like:

{
"dress" {
"ProductName" : "Cotton Dress",
"_id" : 1234567
"Item" : [
{
"size" : "S",
"color" : "black"
},
{
"size" : "M",
"color" : "blue"
}
]
}
}

And what is the mapping for "dress"? I read the doc and is still not
sure.

  1. How does faceting work with a nested document like this? Say I'm
    faceting on "size" and "color",
  • the above document should contribute the values "S", "M" for the
    field "size", and the values "black", "blue" for the field "color"
  • if a user set a filter on "size" to "S", then the above document
    should only contribute the value "black" (but not "blue") for the
    field "color"
    Is the above true? Or did I misunderstand how nested faceting work?
