Perhaps you should try some spelling variations:
kur » kurt, kurs, kaur
kurz » kurtz, kursz, kaurz
kurzt » kurtzt, kurszt, kaurzt, kurze, kuret, kurst
muret » murat, maret, mure
moret » moreto, mores, morel

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