• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - dinh thanh cua dung cong manh ((toan cau) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - dinh thanh cua dung cong manh ((toan cau) OR (toan ban))*".
