Supported languages for JavaScript Search Framework (legacy)

The Coveo Platform supports a wide range of languages across indexing, machine learning models, and user interfaces; however, the depth of linguistic processing varies by language. Support for a language doesn’t constitute a commitment to equivalent relevance, accuracy, or feature parity.

For example, queries and indexed content in languages such as English, French, German, and Spanish achieve higher and more consistent relevance due to more comprehensive language analysis and optimized platform components. Conversely, for other languages that are technically supported but for which the platform isn’t fully optimized, search relevance, generated answers, and overall accuracy can be reduced or be less consistent. Accordingly, language support doesn’t guarantee equal relevance quality, and observed outcomes can vary depending on the language.
