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

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: "((\"die sozialwissenschaft\") OR (\"die sozialwissenschaften\"))".
• Removing quotes may allow a broader search: (( die sozialwissenschaft ) OR ( die sozialwissenschaften )).
• Adding a wildcard symbol may retrieve word variants: (("die sozialwissenschaft") OR ("die sozialwissenschaften"))*.
