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

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 ((die filosofia) OR (e filosofia)) e literatura*".
