• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) xanh - ((thanh truong) OR (thanh trung)) cua song cong tan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc thieu)) xanh - ((thanh truong) OR (thanh trung)) cua song cong tan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (hoc thieu)) xanh - ((thanh truong) OR (thanh trung)) cua song cong tan toan ban*.
