Perhaps you should try some spelling variations:
le litterature » la litterature, de litterature, le letterature
alla filosofia » della filosofia, nella filosofia, la filosofia
als filosofia » la filosofia, a filosofia, masse filosofia
dem studium » das studium, im studium, zum studium
test dem » test der, test des, test de

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: "test dem studium ((als filosofia) OR (alla filosofia)) le litterature".
• Adding a wildcard symbol may retrieve word variants: test dem studium ((als filosofia) OR (alla filosofia)) le litterature*.
