• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cha ve gioi ((can trong) OR (ca trong)) tin ) OR ( tu sach ca me gioi hon luong thi ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach cha ve gioi ((can trong) OR (ca trong)) tin ) or ( tu sach ca me gioi hon luong thi ))*".
