Supported Languages - Coveo Cloud V2

The Coveo Cloud platform can index content written in 43 languages. Coveo Machine Learning (Coveo ML) features and JavaScript Search Framework user interfaces also support a wide array of languages.

  • The Coveo Cloud platform can index other language content as long as:

    • The language uses spaces to separate words

    • The language character set implements Unicode.

    For languages meeting those requirements, most language features are supported, except language detection and stemming.

  • Since result ranking is partially based on summarization and key-concept extraction techniques, English, French, German, and Spanish queries return the most relevant results consistently.

The following table presents the features supported by each language.
