Perhaps you should try some spelling variations:
scale studium » schule studium, scale studies, scale studien
duale studium » duales studium, dualen studium, das studium
der filosofia » de filosofia, e filosofia, di filosofia
de literatura » de litterature, la literatura, y literatura
filosofia de » filosofia del

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: "tests ((scale studium) OR (duale studium)) der filosofia de literatura*".
