Perhaps you should try some spelling variations:
duales studium » das studium
la literature » la litterature, a literature, la literatura
di filosofia » la filosofia, e filosofia
test duales » test doubles, test rules, test oracles
d filosofia » de filosofia, da filosofia, e filosofia

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) OR (di filosofia)) la literature*".
