Perhaps you should try some spelling variations:
literature author » literature arts
literatur oral » literatura oral, literatur moral, literature moral
a literatur » a literature
agenda ii » agenda iii, agenda iv, agenda _
agenda i » agenda _, agenda a, agenda 6
2 benda » 2 bends
ii _ » i _
ii y » ii a, ii 1, ii 3
ii 2 » ii a, i 2, ii 1

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