Perhaps you should try some spelling variations:
als filosofia » alla filosofia, la filosofia, masse filosofia
day studium » das studium, dem studium, d studium
a filosofia » la filosofia, e filosofia, di filosofia
test day » rest day, test data, feast day

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 day studium ((als filosofia) OR (a filosofia)) a literature".
• Adding a wildcard symbol may retrieve word variants: test day studium ((als filosofia) OR (a filosofia)) a literature*.
