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
d filosofia » di filosofia, de filosofia, da filosofia
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 duales studium d filosofia ((de literatur) OR (de litterature))".
• Adding a wildcard symbol may retrieve word variants: test duales studium d filosofia ((de literatur) OR (de litterature))*.
