Perhaps you should try some spelling variations:
literature oral » literature moral, literatura oral, literature morals
1 literatura » 1 literature, 1 literatur, a literatura
y literatura » la literatura
159 agenda » 1979 agenda, 12 agenda, 13 agenda
10 agenda » _ agenda, 10 agent, 7 agenda
agenda ii » agenda iii, agenda i, agenda iv
1 agenda » _ agenda, 7 agenda, 3 agenda

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) OR (10 agenda)) i a literature oral ) OR ( 1 agenda ii ((1 literatura) OR (y literatura)) arab ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((159 agenda) OR (10 agenda)) i a literature oral ) or ( 1 agenda ii ((1 literatura) or (y literatura)) arab ))*".
