Perhaps you should try some spelling variations:
ii filosofia » di filosofia, la filosofia, e filosofia
test duale » test double, test delle, test doubles
test orale » test oracle, test oral, test oracles
studium ii » studium im, studium i, studium die

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((test duale) OR (test orale)) studium ii filosofia ((la litterature) OR (a literature)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((test duale) OR (test orale)) studium ii filosofia ((la litterature) or (a literature))".
• Adding a wildcard symbol may retrieve word variants: ((test duale) OR (test orale)) studium ii filosofia ((la litterature) or (a literature))*.
