Perhaps you should try some spelling variations:
literature author » literature arts
literature oral » literature moral, literatura oral, literature morals
y literature » y literatura, y literatur, key literature
agenda ii » agenda iii, agenda i, agenda _
agenda iv » agenda i, agenda iii, agenda _
benda ii » bamenda ii, anda ii, benda _
2 benda » 2 bends
ii y » ii _, ii a, 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 iv)) a literature oral ) OR ( 2 benda ii y literature author )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 159 ((agenda ii) OR (agenda iv)) a literature oral ) or ( 2 benda ii y literature author ))".
• Adding a wildcard symbol may retrieve word variants: (( 159 ((agenda ii) OR (agenda iv)) a literature oral ) or ( 2 benda ii y literature author ))*.
