Perhaps you should try some spelling variations:
gefasse literatur » ergebnisse literatur
vlaamse literatur » vlaamse literatuur, analyse literatur, phase literatur
nederlandse en » nederland en, nederlanden doen, nederlandse taal

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: ((nederlandse en) OR (nederland den)) ((vlaamse literatur) OR (gefasse literatur)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nederlandse en) or (nederland den)) ((vlaamse literatur) OR (gefasse literatur))".
• Adding a wildcard symbol may retrieve word variants: ((nederlandse en) or (nederland den)) ((vlaamse literatur) OR (gefasse literatur))*.
