Perhaps you should try some spelling variations:
neuen testaments » neuen testament, neues testament, new testaments
neue testament » neues testament, neuen testament, nieuwe testament
literatur des » literatur der, literatur die
her religion » qr religion, our religion, other religions
alten » alter

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: forschungen ((der religion) OR (her religion)) und literatur des alten und ((neuen testaments) OR (neue testament)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "forschungen ((der religion) or (her religion)) und literatur des alten und ((neuen testaments) OR (neue testament))".
• Adding a wildcard symbol may retrieve word variants: forschungen ((der religion) or (her religion)) und literatur des alten und ((neuen testaments) OR (neue testament))*.
