• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach che dan cua cong khong tin ) OR ( ((tu sach) OR (te sach)) cha me gioi o thong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach che dan cua cong khong tin ) or ( ((tu sach) OR (te sach)) cha me gioi o thong tin ))*".
