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 $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.
