Perhaps you should try some spelling variations:
scale studien » scale studies, duale studien, soziale studien
scale student » late student, scale study, scale studies
de filosofica » de filosofia, e filosofica, e filosofia
filosofica a » filosofica da, filosofica e, filosofica _
a literatura » la literatura, a literature, y literatura

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 studien) OR (scale student)) de filosofica a literatura".
• Adding a wildcard symbol may retrieve word variants: tests ((scale studien) OR (scale student)) de filosofica a literatura*.
