The Search interface can be used in most common languages, and you can easily add translations.
Activate the languages that you want to use by enabling them with the toggle. Enabled languages can then be used for translating filter names, sort options, and interface texts under the section Translations in the Advanced Site Search settings. The default language can not be switched off, this one is set via User Experience in the Advanced Site Search settings.
Languages in the Advanced Site Search settings are only available for some versions of Spotler Activate Search. If you don't see this in your account, contact support if you want to know more about this.
