Perhaps you should try some spelling variations:
literatur arab » literatura arab, literature arab, literatur ab
duo literatur » o literatur, iso literatur, abo literatur
bamenda ii » agenda ii, benda ii
amanda ii » amanda l, amanda j, amanda m

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: (( 17 ((amanda ii) OR (bamenda ii)) e literatur a ) OR ( 6 ((amanda ii) OR (bamenda ii)) duo literatur arab )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 17 ((amanda ii) OR (bamenda ii)) e literatur a ) or ( 6 ((amanda ii) OR (bamenda ii)) duo literatur arab ))".
• Adding a wildcard symbol may retrieve word variants: (( 17 ((amanda ii) OR (bamenda ii)) e literatur a ) or ( 6 ((amanda ii) OR (bamenda ii)) duo literatur arab ))*.
