Search suggest results don't match the current language

Make your wiki multilingual and configure the list of supported locales (e.g. en,fr,de). Then search for "wiki" using search suggest. You can get results in French and German if the current language is English. The problem is that the French/German translations can 'hide' the results in English, because the search suggest shows only a limited number of results.

It would be better to display only the results that match the current language.
