• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ma hoa. hieu ve ((cham luc) OR (nhan luc)) va ((thanh ly) OR (thanh ky)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ma hoa. hieu ve ((cham luc) or (nhan luc)) va ((thanh ly) OR (thanh ky)) cua tre".
