Perhaps you should try some spelling variations:
studien der » studie der, studien die, studenten der
eat school » great school, eaton school, coat school
ma school » a school, pa school, _ school
tider mac » tider ma, oder mac, tide may
der mac » der mach, oder mac, der ma

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: (( studien der ((ma school) OR (eat school)) of governance ) OR ( studie ((tider mac) OR (der mac)) school of governance )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( studien der ((ma school) or (eat school)) of governance ) or ( studie ((tider mac) OR (der mac)) school of governance ))".
• Adding a wildcard symbol may retrieve word variants: (( studien der ((ma school) or (eat school)) of governance ) or ( studie ((tider mac) OR (der mac)) school of governance ))*.
