• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (doi chieu)) xanh - ((hanh tranh) OR (canh tranh)) hoa khong huong dan thanh cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (doi chieu)) xanh - ((hanh tranh) OR (canh tranh)) hoa khong huong dan thanh cac".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (doi chieu)) xanh - ((hanh tranh) OR (canh tranh)) hoa khong huong dan thanh cac*.
