• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc trinh) OR (hoc tinh)) tinh - nhanh sinh cua cong cong ban ((than cap) OR (thanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc trinh) or (hoc tinh)) tinh - nhanh sinh cua cong cong ban ((than cap) OR (thanh cac))*".
