• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly nang ((x hoi) OR (xa hoi)). hieu ((va cam) OR (va cao)) tuc gia thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly nang ((x hoi) OR (xa hoi)). hieu ((va cam) or (va cao)) tuc gia thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: thu sach ly nang ((x hoi) OR (xa hoi)). hieu ((va cam) or (va cao)) tuc gia thanh vi cua te*.
