• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chieu) OR (theo chu)) xanh - ((hanh dan) OR (thanh dan)) va dung cong ban than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (theo chu)) xanh - ((hanh dan) OR (thanh dan)) va dung cong ban than cap*".
