Perhaps you should try some spelling variations:
literatur oral » literatura oral, literatur moral, literature moral
1 literatura » 1 literature, 1 literatur, y literatura
literatura a » literatura y, literatura e, literatura i
a literatur » a literature
159 agenda » 1979 agenda, 1 agenda, 10 agenda
agenda i » agenda _, agenda a, agenda 6
2 agenda » _ agenda, 7 agenda, 1 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 literatur oral ) OR ( 2 agenda i 1 literatura a ))*.
