A way to show what object in an array in the document matched the query.

[labadcloyd]

I have a document in an index like so:

{
            "id": "9ef0e1cb-0c15-4cf0-a655-6e83af162bcb",
            "ingredient_mapping": [
                {
                    "ingredient_name": "Croissants",
                    "ingredient_variant_Name": "cheese",
                },
                { 
                    "ingredient_name": "Croissants", 
                    "ingredient_variant_Name": "butter", 
                },
                { 
                    "ingredient_name": "Croissants",
                    "ingredient_variant_Name": "apple", 
                }
            ],
            "name": "Croissants",
            "name_owner": "USDA"
}

If im going to search for the term "Croissants butter" it would most likely return this entire object. But if there was a way to know at which index of the array "ingredient_mapping" the match was then it would really help a lot.

This is similar to showMatchesPosition but the index of the object in the array would be returned, not the index of the string.

EDIT: I've queried the above document with showMatcherPosition and this is what it returns:

{
  "hits": [
    {
      "_matchesPosition": {
        "ingredient_details.ingredient_variant_name": [
          {
            "length": 6,
            "start": 0
          }
        ],
        "name": [
          {
            "length": 10,
            "start": 0
          }
        ]
      },
      "id": 129,
      "ingredient_details": [
        {
          "ingredient_mapping_id": 1950,
          "ingredient_subvariant_name": "",
          "ingredient_variant_name": "cheese"
        },
        {
          "ingredient_mapping_id": 1951,
          "ingredient_subvariant_name": "",
          "ingredient_variant_name": "butter"
        },
        {
          "ingredient_mapping_id": 1952,
          "ingredient_subvariant_name": "",
          "ingredient_variant_name": "apple"
        }
      ],
      "name": "Croissants",
      "name_owner": "USDA"
    }
  ],
  "estimatedTotalHits": 1,
  "limit": 20,
  "processingTimeMs": 1,
  "query": "croissant butter"
}

Is there a way we can add the index to the array in the "_matchesPosition" field data?
