MongoDB offers a 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 language value of "none", then the text search
uses simple tokenization with no list of stop words and no stemming.
