Perhaps you should try some spelling variations:
duales studium » das studium
filosofia la » filosofia le, filosofica da, filosofia das
filosofia da » filosofia del, filosofia e, filosofia della
filosofia de » filosofia del
test duales » test doubles, test rules, test oracles

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 _ ((filosofia la) OR (((filosofia da) OR (filosofia de)))) literatura".
• Adding a wildcard symbol may retrieve word variants: test duales studium _ ((filosofia la) OR (((filosofia da) OR (filosofia de)))) literatura*.
