Text Search Languages on Self-Managed Deployments

This version of the documentation is archived and no longer supported. To upgrade your 6.0 deployment, see the MongoDB 7.0 upgrade procedures.

Note

This page describes text query capabilities for self-managed (non-Atlas) deployments. For data hosted on MongoDB Atlas, MongoDB offers an improved full-text query solution, Atlas Search and a vector search solution, Atlas Vector Search.

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.
