• The words AND, OR and NOT may confuse the search; try adding quotes: "((30 trieu) or (mot trieu)) tinh - hanh tang cua nhung cong tap ((doan cao) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ((30 trieu) or (mot trieu)) tinh - hanh tang cua nhung cong tap ((doan cao) OR (toan cao))*.
