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