• If you are trying to use Boolean operators, they must be ALL CAPS: theo thu sang - lan doanh ((cua thong) OR (cua tong)) cong ((van tan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo thu sang - lan doanh ((cua thong) OR (cua tong)) cong ((van tan) or (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo thu sang - lan doanh ((cua thong) OR (cua tong)) cong ((van tan) or (manh toan)) cau*.
