Text Search Languages
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
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
ISO 639-1 (Two letter codes)
If you specify a language value of
"none", then the text search
uses simple tokenization with no list of stop words and no stemming.
