Usage of _explain API with nested documents for TF/IDF computation?

[starblow1 (Thomas Mundt)]

Hello community,

is it possible to use the _explain API with a nested object to get TF/IDF values?
I made a POST request with POSTMAN to my index using indexname/typename/_explain

I used the following body to no avail: (

{
  "query": {
    "bool": {
      "must": [
        {
          "nested": {
            "path": "equipments", 
            "query": {
            	"term" : { "equipments.subject" : "PC" }
            }
          }
        }
      ]
    }
  }
}
