I'm using multilingual properties inside grid layout with doc type grid editors which gives the below code in umbraco.config

    <gridContent><![CDATA[{
  "name": "1 column layout",
  "sections": [
    {
      "grid": 12,
      "allowAll": true,
      "rows": [
        {
          "label": "row-12",
          "name": "row-12",
          "areas": [
            {
              "grid": 12,
              "gridClasses": "",
              "hasConfig": false,
              "controls": [
                {
                  "value": {
                    "dtgeContentTypeAlias": "gridRte",
                    "value": {
                      "name": "Metin",
                      "metin": {
                        "values": {
                          "tr-TR": "<p>Lorem ipsum</p>"
                        },
                        "dtdGuid": "c4a9be79-a5d3-4a2c-a6c4-ef7a14e4aa0d"
                      }
                    },
                    "id": "4ec95e3c-b51b-c406-05a0-30f20768d6ed"
                  },
                  "editor": {
                    "alias": "docType"
                  },
                  "active": true
                }
              ],
              "active": true,
              "hasActiveChild": true
            }
          ],
          "hasConfig": false,
          "id": "cf1c0c96-6c31-d9ee-ca12-0d36d7bea325",
          "hasActiveChild": true,
          "active": true
        }
      ]
    }
  ]
}]]></gridContent>

Properties are indexed when used directly in document type level. I need to index multilingual text content inside grid layout.

Any advice?
