It's easy as documented in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21).

```auto
DELETE index
PUT index/_doc/1
{
  "foo": "bar"
}
GET index/_search
{
  "query": {
    "match": {
      "foo": "bar"
    }
  }
}

```

But just with your mapping, data and then with the [Cardinality aggregation | Elasticsearch Guide [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-cardinality-aggregation.html). In that link you also have some "Kibana" examples.
