Supported Languages - Coveo Cloud
The Coveo Platform can index content written in 57 languages. Coveo Machine Learning (Coveo ML) features and Coveo JavaScript Search Framework user interfaces also support a wide array of languages.
-
The Coveo Platform can index other language content as long as:
-
The language uses spaces to separate words.
-
The item encodes characters in 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.
