Perhaps you should try some spelling variations:
kur » kurz, kurt, kurs
kuret » kurzet, kurtet, kurset, kurt, kuren, furet
kurzttzzt » kurzzttzzt, kurtzttzzt, kurszttzzt
kurssen » kurzssen, kurtssen, kursssen, kursen, courssen
muret » murat, maret, moret

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((kur OR (((kuret OR muret) OR kurzttzzt) OR kurssen)) OR kaursse).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((kur or (((kuret OR muret) or kurzttzzt) or kurssen)) or kaursse)".
• Adding a wildcard symbol may retrieve word variants: ((kur or (((kuret OR muret) or kurzttzzt) or kurssen)) or kaursse)*.
