1 literatura » 1 literature, 1 literatur, a literatura
y literatura » la literatura
159 agenda » 1979 agenda, 1 agenda, 10 agenda
agenda ii » agenda iii, agenda iv, agenda 21
agenda i » agenda a, agenda 6, agenda 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 i a literature oral ) OR ( 1 ((agenda ii) OR (agenda _)) ((1 literatura) OR (y literatura)) arab ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 159 agenda i a literature oral ) or ( 1 ((agenda ii) OR (agenda _)) ((1 literatura) or (y literatura)) arab ))*".
