• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (((so sach) OR (bo sach)))) thu lang xa hoi. hieu ve cac duc gia anh vi cau treo~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (((so sach) OR (bo sach)))) thu lang xa hoi. hieu ve cac duc gia anh vi cau treo~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (((so sach) OR (bo sach)))) thu lang xa hoi. hieu ve cac duc gia anh vi cau treo*.
