• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hiem ngan - thanh trung tuan ((hang song) OR (((hang nong) OR (thang long)))) van toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hiem ngan - thanh trung tuan ((hang song) or (((hang nong) OR (thang long)))) van toan ban*".
