Perhaps you should try some spelling variations:
literature oral » literature moral, literatura oral, literature morals
1 literatura » 1 literatur, y literatura, a literatura
159 agenda » 1979 agenda, 10 agenda, 12 agenda
agenda i » agenda _, agenda a, agenda 6
2 agenda » _ agenda, 7 agenda, 3 agenda
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 i a literature oral ) OR ( ((2 agenda) OR (1 agenda)) ii ((1 literatura) OR (1 literature)) arab ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 159 agenda i a literature oral ) or ( ((2 agenda) OR (1 agenda)) ii ((1 literatura) or (1 literature)) arab ))*".
