Perhaps you should try some spelling variations:
literatura oral » literature moral, literatura a, literatura del
a literatura » la literatura, a literature, y literatura
literatur ab » literatur a, literatur a1, literatur am
1 literatur » 11 literatur, 1 literature
159 agenda » 1979 agenda, 10 agenda, 12 agenda
1 agenda » _ agenda, 7 agenda, 3 agenda
agenda 2 » agenda 21, agenda a, agenda 6

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 _ a literatura oral ) OR ( 1 agenda 2 1 literatur ab ))*.
