Got it, you want to limit the fields returned in each document based on the length of their values. In Elasticsearch, you can achieve this using the `source` parameter to specify which fields to include in the search response, along with scripting to filter the fields based on their length. Here's an example:

```json
{
  "_source": {
    "includes": [
      "*",
      "field1",
      "field2"
    ],
    "script_fields": {
      "short_fields": {
        "script": {
          "source": """
            def result = [:];
            for (entry in params['_source'].entrySet()) {
              if (entry.getValue() instanceof String && entry.getValue().length() < params.limit) {
                result[entry.getKey()] = entry.getValue();
              }
            }
            return result;
          """,
          "lang": "painless",
          "params": {
            "limit": 50
          }
        }
      }
    }
  }
}
```

In this example:
- `"_source"` includes all fields by default (`"*"`) and then explicitly specifies `field1` and `field2` to be included in the response.
- `script_fields` defines a custom field (`short_fields`) generated by a script.
- The script iterates over each field in the document (`params['_source'].entrySet()`) and checks if it's a string and if its length is less than the specified limit (`params.limit`).
- If a field meets the criteria, it's added to the `short_fields` result.

Adjust the field names, character limit, and any other parameters according to your specific use case.

{
  "_source": false,
  "script_fields": {
    "short_fields": {
      "script": {
        "source": """
          def result = [:];
          for (entry in doc.entrySet()) {
            if (entry.getValue() instanceof String && entry.getValue().length() < params.limit) {
              result[entry.getKey()] = entry.getValue();
            }
          }
          return result;
        """,
        "lang": "painless",
        "params": {
          "limit": 50
        }
      }
    }
  }
}
