# DefaultLanguageType

The default language type (language and encoding) to use for documents of unspecified language.

IDOL Server uses this language type for documents when:

- it cannot read the language type of a document from a specified field.
- the LanguageType parameter is not specified in the action.
- automatic language detection is disabled.

`DefaultLanguageType` also specifies the default for the LanguageType parameter in actions such as Query and Summarize.

If you do not set `DefaultLanguageType` and you do not specify the language type in actions, IDOL Server uses the first language type defined in the `[MyLanguage]` section.

If you do not set the DefaultEncoding configuration parameter and you do not set the OutputEncoding action parameter, IDOL Server uses the encoding specified in the LanguageType action parameter, or in the `DefaultLanguageType` configuration parameter if you do not use the LanguageType action parameter.

NOTE: If the encoding of a document is found, but the language is not, IDOL Server can apply a `[General]` language, if it is defined, and if automatic language detection is activated.
