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