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