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
e filosofia » la 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 (duale studien)) e filosofia la literatura".
• Adding a wildcard symbol may retrieve word variants: testo ((scale studien) OR (duale studien)) e filosofia la literatura*.
