Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
test orale » test oracle, test oral, test oracles
studium dd » studium ad, studium der, studium des
studium d » studium ad, studium _, studium 1

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 orale ((studium dd) OR (studium d)) filosofia la literatura*".
