• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (thi chieu)) xanh - hanh tinh cua dung song ((van tuan) OR (van ban)) ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (thi chieu)) xanh - hanh tinh cua dung song ((van tuan) OR (van ban)) ban*.
