Perhaps you should try some spelling variations:
literatura oral » literature moral, literatura a, literatura del
literature arts » literature part, literature a, literature cited
literatur oral » literatur moral, literature moral, literature morals
159 agenda » 1979 agenda, 1 agenda, 10 agenda
agenda iii » agenda i
2 benda » 2 bends
iii a » iii _
ii y » ii _, ii a, ii 1
ii 2 » ii _, ii a, i 2

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