nhung song » nhung cong, nhung bong, nhung chong

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - ((hanh trang) OR (thanh trung)) cua nhung song ((van tuan) OR (van quan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - ((hanh trang) or (thanh trung)) cua nhung song ((van tuan) OR (van quan)) cao~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - ((hanh trang) or (thanh trung)) cua nhung song ((van tuan) OR (van quan)) cao*.
