Hi,

Can I create a mapping and use wildcards in the fields name? For example, I  
want to create a template with the following mapping:

{

"user": {

"dynamic": "false",

"properties": {

"email": { "type":"string" },

"\*\_metadata": {

"type": "object",

"dynamic": "true"

}

}

}

}

Then, the "foo\_metadata", "bar\_metadata", etc fields will be mapped.

Is it possible?

Hi,

You try to use “dynamic\_templates” .

> **[Mapping root object type | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-root-object-type.html#_dynamic_templates)**

I hope that those help you out.
