• If you are trying to use Boolean operators, they must be ALL CAPS: hoa chinh sach - ((thanh thuong) OR (thanh tung)) ((quan tong) OR (quan long)) song van tuan tai~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoa chinh sach - ((thanh thuong) or (thanh tung)) ((quan tong) OR (quan long)) song van tuan tai~".
• Adding a wildcard symbol may retrieve word variants: hoa chinh sach - ((thanh thuong) or (thanh tung)) ((quan tong) OR (quan long)) song van tuan tai*.
