Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, soziale studien
duale studien » duale studium, duales studium, dualen studium
des filosofia » de filosofia, e filosofia, di filosofia
de literature » de litterature, de lite'rature, de 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: "sets ((scale studien) OR (duale studien)) des filosofia de literature".
• Adding a wildcard symbol may retrieve word variants: sets ((scale studien) OR (duale studien)) des filosofia de literature*.
