Perhaps you should try some spelling variations:
literatur oral » literatura oral, literatur moral, literature moral
de literatura » de litterature, la literatura, a literatura
y literatura » la literatura
159 amanda » 1 amanda, 17 amanda
2 amanda » _ amanda, 1 amanda, 6 amanda
amanda j » amanda l, amanda m
ii a » i a

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 amanda ((ii a) OR (ii _)) literatur oral ) OR ( 2 amanda j ((de literatura) OR (y literatura)) arab )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 159 amanda ((ii a) or (ii _)) literatur oral ) or ( 2 amanda j ((de literatura) OR (y literatura)) arab ))".
• Adding a wildcard symbol may retrieve word variants: (( 159 amanda ((ii a) or (ii _)) literatur oral ) or ( 2 amanda j ((de literatura) OR (y literatura)) arab ))*.
