Perhaps you should try some spelling variations:
duales studium » das studium
de litterature » la litterature, et litterature
de literatur » de literatura, de literatuur, erde literatur
test duales » test doubles, test rules, test oracles
1 filosofia » e filosofia, a filosofia, y filosofia
studium 1 » studium _, studium 3, studium 8

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 duales studium 1 filosofia ((de literatur) OR (de litterature))".
• Adding a wildcard symbol may retrieve word variants: test duales studium 1 filosofia ((de literatur) OR (de litterature))*.
