Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
a literatura » a literature, y literatura, a literatur
1 filosofia » e filosofia, a filosofia, y filosofia
studium 1 » studium _, studium 3, studium 8
test das » test des, test day, testen das
west das » westen das, west ak, west a

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 das) OR (west das)) studium 1 filosofia ((a literatura) OR (la literatura)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((test das) or (west das)) studium 1 filosofia ((a literatura) OR (la literatura))".
• Adding a wildcard symbol may retrieve word variants: ((test das) or (west das)) studium 1 filosofia ((a literatura) OR (la literatura))*.
