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

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