Perhaps you should try some spelling variations:
studium das » studium des, studium der, studium als
studium die » studium der, studium des
filosofia e » filosofia de, filosofia del
e literatur » die literatur
testo das » test das, tests das, testen das

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 das ((studium das) OR (studium die)) filosofia e literatur*".
