Perhaps you should try some spelling variations:
literature arab » literatura arab, literature arts, literature art
literatur moral » literature moral, literature morals, literatura oral
y literature » y literatura, y literatur, key literature
159 agenda » 1979 agenda, 1 agenda, 10 agenda
agenda ii » agenda iii, agenda i, agenda iv
benda ii » bamenda ii, eda ii, anda ii
iv a » iv _, i a
ii a » ii _, i a

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