Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, soziale studien
duale studien » duale studium, duales studium, dualen studium
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
a filosofia » la filosofia, e filosofia, di 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: "quito ((scale studien) OR (duale studien)) a filosofia la literatura*".
