Perhaps you should try some spelling variations:
de litterature » la litterature, et litterature
de literatur » de literatura, de literatuur, erde literatur
day studium » das studium, dem studium, d studium
e filosofia » la filosofia
studium e » studium _, studium 1, studium 3
rest day » great day, feast day, rest data

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: "rest day studium e filosofia ((de literatur) OR (de litterature))".
• Adding a wildcard symbol may retrieve word variants: rest day studium e filosofia ((de literatur) OR (de litterature))*.
