# General Language

You can specify a General language, which IDOL uses for documents with an unconfigured language, but whose encoding is identified. IDOL classifies documents as the General language when:

- IDOL Server cannot read the language type nor the encoding of a document from a specified field

- Automatic Language Detection is enabled.

If IDOL Server detects an unconfigured language type, it indexes to the equivalent `General` language type for that encoding, if it exists. It also logs a warning message in the index log so that you can add an appropriate language type to the configuration file. IDOL also indexes unknown languages to the `General` language type for the encoding, if it exists. If the encoding is unknown, IDOL indexes the document to the default language.

You can configure IDOL Server to discard documents that have unconfigured languages, even if a General language exists for that encoding. See DiscardUnconfiguredLanguagesAtIndex.
