• The words AND, OR and NOT may confuse the search; try adding quotes: "((30 trieu) or (mot trieu)) tinh - ((hanh tang) OR (anh tang)) cua bang song anh tuan cu~".
• Adding a wildcard symbol may retrieve word variants: ((30 trieu) or (mot trieu)) tinh - ((hanh tang) OR (anh tang)) cua bang song anh tuan cu*.
