• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sang - canh doanh ((luan thong) OR (luat thong)) cong ((xuan toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - canh doanh ((luan thong) OR (luat thong)) cong ((xuan toan) or (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - canh doanh ((luan thong) OR (luat thong)) cong ((xuan toan) or (dan than)) cau*.
