Perhaps you should try some spelling variations:
literature authors » literature author, literature authorship, literary authors
literature oral » literature moral, literatura oral, literature morals
y literature » y literatura, y literatur, key literature
159 agenda » 1979 agenda, 10 agenda, 12 agenda
bamenda ii » agenda ii, amanda ii, benda ii
2 bamenda » _ bamenda
1 agenda » _ agenda, 7 agenda, 3 agenda
iv a » iv _, i a, ii a
ii y » ii _, ii a, ii 1

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) OR (1 agenda)) iv a literature oral ) OR ( 2 bamenda ii y literature authors ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((159 agenda) OR (1 agenda)) iv a literature oral ) or ( 2 bamenda ii y literature authors ))*".
