Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, soziale studien
duale studien » duale studium, duales studium, dualen studium
de literatura » de litterature, la literatura, y literatura
es filosofia » e filosofia, em filosofia, la filosofia
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: "texto ((scale studien) OR (duale studien)) es filosofia de literatura".
• Adding a wildcard symbol may retrieve word variants: texto ((scale studien) OR (duale studien)) es filosofia de literatura*.
