# Text-Free Queries

By default, query actions that do not contain any query text return results in the encoding specified in the `DefaultLanguageType` parameter. If any of the query results are not compatible with this encoding, IDOL Server indicates this in the results.

If you want a query action to return results in a specific encoding, you can add the `OutputEncoding` parameter to your query. IDOL Server converts all results to this encoding, as long as they are compatible with it. If any of the query results are not compatible with this encoding, IDOL Server returns an appropriate message. You can specify a default value for the `OutputEncoding` parameter in the `DefaultEncoding` configuration parameter.

For example:

    http://12.3.4.56:4000/action=Suggest&ID=9016&OutputEncoding=EASTERNEUROPEAN_ISO

In this example, IDOL Server converts all query results to `EASTERNEUROPEAN_ISO`.
