Text Search Languages on Self-Managed Deployments

This version of the documentation is archived and no longer supported. To upgrade your 5.0 deployment, see the MongoDB 6.0 upgrade procedures.

MongoDB offers a premium full-text search solution, MongoDB Atlas Search, for data hosted on MongoDB Atlas. A legacy text search capability is available for users self-managing MongoDB deployments.

The text index and the $text operator may be used with the following languages, and accepts either the two-letter ISO 639-1 language code or the long form of the language name:

Language Name	ISO 639-1 (Two letter codes)
`danish`	`da`
`dutch`	`nl`
`english`	`en`
`finnish`	`fi`
`french`	`fr`
`german`	`de`
`hungarian`	`hu`
`italian`	`it`
`norwegian`	`nb`
`portuguese`	`pt`
`romanian`	`ro`
`russian`	`ru`
`spanish`	`es`
`swedish`	`sv`
`turkish`	`tr`

If you specify a default_language value of none, the text index parses through each word in the field, including stop words, and ignores suffix stemming.
