elasticsearch - Aggregating on entities within Kibana using values in nested entities -

an elasticsearch index contains product entity. each product has array of components entities. component may contain optional outofstock field.

given following example:

"product":     "name": "blue_toy"    "components": [     {        "partnumber": "100"        "supplier": "smith , sons"        "outofstock": "true"     }      {        "partnumber": "200"        "supplier": "smith , sons"      }] }   "product":     "name": "green_toy"    "components": [     {        "partnumber": "300"        "supplier": "smith , sons"     }] } 

blue_toy cannot built because 1 part unavailable.

i want show in chart how many products cannot build, opposed number can built.

given if 1 component unavailable entire product cannot built, in above example distribution 50% - 50%.

note different how many components of total set are of stock (which 33% - 66%).

in essense, question how mark or flag root entity based on contents of 1 of nested entities.

how 1 in kibana?

thanks

i dont know if fit in exemple once did have similar problem solved "copy_to" parameter.

in exemple, have change mapping of product add "copy_to" "outofstock" field.

it'll create field (with specified name) in root document "outofstock" value.

this field add @ indexing time , can if field created "copy_to" "true" product cannot built.
