• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - ((hanh trang) OR (canh tranh)) cua cong cong ban hang dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - ((hanh trang) OR (canh tranh)) cua cong cong ban hang dau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - ((hanh trang) OR (canh tranh)) cua cong cong ban hang dau*.
