• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - canh ((tranh cua) OR (doanh cua)) nhung cong tan ((toan cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - canh ((tranh cua) OR (doanh cua)) nhung cong tan ((toan cau) or (than cap))*.
