Perhaps you should try some spelling variations:
studien der » studie der, studenten der
studien die » studie die
ma school » a school, pa school, roma school
tider ma » tide a, tider i, tider og
tider a » tide a, tider i, tider og

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