Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, duale studien
de filosofia » e filosofia, di filosofia, la filosofia
e literatura » de literatura, y literatura, a literatura
e literatur » die literatur
sets scale » sets scaled, sets scales, set scale
studien de » studien der, studien die, studien des

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "sets scale studien de filosofia ((e literatura) OR (e literatur))".
• Adding a wildcard symbol may retrieve word variants: sets scale studien de filosofia ((e literatura) OR (e literatur))*.
