• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - thanh trung va nhung cong thanh ((san tap) OR (han tap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - thanh trung va nhung cong thanh ((san tap) OR (han tap))*.
