Perhaps you should try some spelling variations:
kur » kurs, kaur
kuret » kurset, kauret, kuren, muret, buret
kurz » kursz, kaurz
kurt » kurst, kaurt
kurzssz » kurszssz, kaurzssz, kurzsitz
furet » furent, furst, foret

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 furet) OR kurz) OR kurt) OR kurzssz)) OR kaursse).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((kur or ((((kuret OR furet) or kurz) or kurt) or kurzssz)) or kaursse)".
• Adding a wildcard symbol may retrieve word variants: ((kur or ((((kuret OR furet) or kurz) or kurt) or kurzssz)) or kaursse)*.
