Hi,

In order to support multi-lingual documents, we stored them with the suffix of the language code, such as:  
{  
"description\_EN": "My Description",  
"description\_FR": "Ma Description"  
}

We do not know in advance, in which language(s) documents are generated and we support up to 24 languages. Mappings for the 24 languages were created.

Therefore my question:

How can I run a query against all documents, not knowing the "field name" **suffix**?

I would need something like;

..."wildcard": {  
"description\_\*.keyword": {  
"wildcard": "_a_"  
}  
}

but this does not work...

Any help would be more than welcome.

Many thanks in advance,

One way which could work is using the [query\_string](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html) / [simple\_query\_string](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-simple-query-string-query.html) query.

```
{
  "query": {
    "query_string": {
      "query": "a*",
      "fields": [
          "description_*"
        ]
    }
  }
}

```

They allow wildcards in both field names and query terms
