Perhaps you should try some spelling variations:
moderne studien » modern studies, modern studio, modernist studies
modell studien » model studies, models studies, modern studies
le literatura » la literatura, de literatura, e literatura
filosofia le » filosofia de, filosofia e, filosofia del
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: "tesi ((modell studien) OR (moderne studien)) e filosofia le literatura".
• Adding a wildcard symbol may retrieve word variants: tesi ((modell studien) OR (moderne studien)) e filosofia le literatura*.
