• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - anh tang cua dong cong tan ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - anh tang cua dong cong tan ((toan cau) or (toan cao))*.
