You specifically meant: http://docs.mongodb.org/manual/tutorial/create-text-index-on-multi-language-collection/#use-any-field-to-specify-the-language-for-a-document I suppose, which allows you to override the language for a whole document with a specific field's value.
What you want from your question, you can not do yet in MongoDB, but this feature is planned for the upcoming version of MongoDB. You can track the ticket at https://jira.mongodb.org/browse/SERVER-9390
