Normalizer for Keyword datatype is **_Experimental_** currently.

[https://www.elastic.co/guide/en/elasticsearch/reference/current/keyword.html#keyword-params](https://www.elastic.co/guide/en/elasticsearch/reference/current/keyword.html#keyword-params)

Is there another way to lowercasing value of keyword field?

this is mapping

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

```

Add documents

```
POST {
  "country":"US"
}
POST {
  "country":"us"
}

```

Now, want to search both US and us.  
this expected to return two document above.

```
GET
search?q=country:us

```

How can I do that without using experimental feature?

You can use ingest node and lowercase your field at index time.
