Perhaps you should try some spelling variations:
literatur author » literature author, literatur autor, literature authors
literatur oral » literatura oral, literatur moral, literature moral
a literatur » a literature
y literatur » y literatura
159 agenda » 1979 agenda, 1 agenda, 10 agenda
agenda ii » agenda iii, agenda i, agenda iv
2 bends » 2 beards
ii a » ii _, i a
ii y » ii _, ii 1, ii 2

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: (( 159 agenda ii a literatur oral ) OR ( ((2 benda) OR (2 bends)) ii y literatur author )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 159 agenda ii a literatur oral ) or ( ((2 benda) OR (2 bends)) ii y literatur author ))".
• Adding a wildcard symbol may retrieve word variants: (( 159 agenda ii a literatur oral ) or ( ((2 benda) OR (2 bends)) ii y literatur author ))*.
