Perhaps you should try some spelling variations:
filosofia de » filosofia del
de literatur » de literatura, de literatuur, de litterature
feast day » fast day, first day, last day
studium 1 » studium _, studium 3, studium im
studium 8 » studium _, studium 3, studium im

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: "feast day ((studium 1) OR (studium 8)) filosofia de literatur".
• Adding a wildcard symbol may retrieve word variants: feast day ((studium 1) OR (studium 8)) filosofia de literatur*.
