Hello!

I'd like to set all fields type as `keyword` except some custom fields.

```auto
"properties": {
  "field1": { "type" : "text" },
  "*": { "type" : "keyword" }
}

```

doesn't work ant the fields mapping dynamically.

Is there any way to solve the task?

Have a look at [Dynamic templates | Elasticsearch Guide [7.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-templates.html)
