I have the mapping

```auto
{
  "test" : {
    "mappings" : {
      "properties" : {
        "description" : {
          "type" : "text"
        },
        "location" : {
          "type" : "keyword",
          "index" : false
        },
        "title" : {
          "type" : "text"
        }
      }
    }
  }
}

```

and I want to update the `index` parameter of the `location` field to `true`

I am trying

```auto
PUT /test/_mapping
{
  
    "properties": {
        "location": { 
            "type": "keyword",
            "index": true
        }
    }
  
}

```

and I am getting

```auto
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Mapper for [location] conflicts with existing mapping:\n[mapper [location] has different [index] values]"}],"type":"illegal_argument_exception","reason":"Mapper for [location] conflicts with existing mapping:\n[mapper [location] has different [index] values]"},"status":400}

```

How to update the `index` parameter?
