Perhaps you should try some spelling variations:
literatur arab » literature arab, literatura arab, literatur ab
159 bamenda » 159 amanda
y literatur » y literatura
bamenda ii » agenda ii, amanda ii, benda ii
2 benda » 2 bends

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