Perhaps you should try some spelling variations:
scale studien » scale student, duale studien, soziale studien
scale studies » scale study
e literatura » de literatura, y literatura, e literatur
e filosofia » la filosofia
filosofia e » 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: "set ((scale studien) OR (scale studies)) e filosofia e literatura*".
