Perhaps you should try some spelling variations:
neuen testaments » neuen testament, neues testament, neue testament
orbis antiquus » orbis antiqui, urbis antiquae
testamentum 1 » testamentum a, testamentum _, testamentum f
testamentum 2 » testamentum a, testamentum _, testamentum f
studien fur » studie fur, studenten fur
umwelt des » umwelt der

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: novum ((testamentum 1) OR (testamentum 2)) orbis antiquus : studien fur ((umwelt des) OR (umwelt die)) neuen testaments.
• The words AND, OR and NOT may confuse the search; try adding quotes: "novum ((testamentum 1) or (testamentum 2)) orbis antiquus : studien fur ((umwelt des) OR (umwelt die)) neuen testaments".
• Adding a wildcard symbol may retrieve word variants: novum ((testamentum 1) or (testamentum 2)) orbis antiquus : studien fur ((umwelt des) OR (umwelt die)) neuen testaments*.
