Perhaps you should try some spelling variations:
scale studien » scale student, duale studien, soziale studien
scale studies » scale study
le literatura » la literatura, de literatura, e literatura
filosofia le » filosofia de, filosofia e, filosofia del
3 filosofia » e filosofia, a filosofia, y filosofia

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: "testo ((scale studien) OR (scale studies)) 3 filosofia le literatura".
• Adding a wildcard symbol may retrieve word variants: testo ((scale studien) OR (scale studies)) 3 filosofia le literatura*.
