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