Perhaps you should try some spelling variations:
der filosofia » de filosofia, e filosofia, di filosofia
e literatura » de literatura, y literatura, e literatur
filosofia e » filosofia de, filosofia del
tests des » tests der, tests test, testen des
test des » test der, test test

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: "((tests des) OR (test des)) studium der filosofia e literatura*".
