• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - anh mang cua ((hang cong) OR (bang cong)) san ((toan tap) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - anh mang cua ((hang cong) OR (bang cong)) san ((toan tap) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - anh mang cua ((hang cong) OR (bang cong)) san ((toan tap) or (van ban))*.
