Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
studium e » studium _, studium 3, studium 8
studium 1 » studium _, studium 3, studium 8
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 e) OR (studium 1)) filosofia la literatura".
• Adding a wildcard symbol may retrieve word variants: test dem ((studium e) OR (studium 1)) filosofia la literatura*.
