I want add mapping to synonym analyzer by perform this operation

```auto
PUT /my_index/_mapping/items
{
      "items": {
        "properties": {
          "judul": {
            "type": "text",
            "analyzer": "synonym"
          }
        }
      }
}

```

But, I got this error

```auto
{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Mapper for [judul] conflicts with existing mapping in other types:\n[mapper [judul] has different [analyzer]]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Mapper for [judul] conflicts with existing mapping in other types:\n[mapper [judul] has different [analyzer]]"
  },
  "status": 400
}

```

Here is my `localhost:9200/my_index/_mapping/`

```auto
{
  "my_index": {
    "mappings": {
      "items": {
        "properties": {
          .
          .
          .
          "judul": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          .
          .
          .
        }

You can't update an existing field and change the `analyzer`.

You need to DELETE the index and create it again.
