Perhaps you should try some spelling variations:
"die sozialwissenschaften" » "den sozialwissenschaften", "der sozialwissenschaften", "und sozialwissenschaften"
"und sozialwissenschaft" » "und sozialwissenschaften", "und sozialwissenschaftler", "der sozialwissenschaft"

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: (("die sozialwissenschaften") OR ("und sozialwissenschaft"))*.
• Removing quotes may allow a broader search: (( die sozialwissenschaften ) or ( und sozialwissenschaft ))*.
