Hi @MaulishShah.
I am not sure, what you intent to do, but I will try to answer your question anyway 😉

fielddata is a data structure for text fields, that is created in-memory, the first time a specific field is part of a build of aggregations, sorting, or in a script. For more details take a look.

In your example, it seems you want to enable fielddata for whole type. That will not work, cause it is defined only on text fields within you specific type.

Anyway, this example enables fielddata for field, let's say rating:

PUT schools/_mapping/school
{
  "properties": {
    "rating": { 
      "type": "text",
      "fielddata": true
    }
  }
}

The mapping will be changed afterwords to something like:

{
  "schools" : {
    "mappings" : {
      "school" : {
        "properties" : {
          "city" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },
          "description" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },
          "fees" : {
            "type" : "long"
          },
          "location" : {
            "type" : "float"
          },
          "name" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },
          "rating" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            },
            "fielddata" : true
          },
          "state" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },
          "street" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },
          "tags" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          },
          "zip" : {
            "type" : "text",
            "fields" : {
              "keyword" : {
                "type" : "keyword",
                "ignore_above" : 256
              }
            }
          }
        }
      }
    }
  }
}

Hope that helps somehow 😉
