• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) xanh - anh nang cua bang cong tap ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) xanh - anh nang cua bang cong tap ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) xanh - anh nang cua bang cong tap ((toan cau) OR (toan cao))*.
