• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (theo chieu)) xanh - thanh trung va thong song ((van tan) OR (van ban)) ca~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (theo chieu)) xanh - thanh trung va thong song ((van tan) OR (van ban)) ca~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (theo chieu)) xanh - thanh trung va thong song ((van tan) OR (van ban)) ca*.
