Assume that the defined mapping in ES2.3 has this format.

```auto
"properties": {
   "accountId": {
        "type": "string",
        "index": "not_analyzed"
   }
}

```

Is it equivalent to this in ES 7.8 version?

```auto
"properties": {
   "accountId": {
        "type": "text"
   }
}

```

What parameters can I choose for "index" if it is still in use?

No, it should be equivalent to this:

```
"properties": {
   "accountId": {
        "type": "keyword"
   }
}
```

</div>

```auto
"fields": {
        "length": {
          "type": "token_count",
          "analyzer": "proper_name"
        }
}

```

and how do I debug this "analyzer" to match an equivalent expression in ES 7.8?
