• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ty nang ((x hoi) OR (o hoi)). hieu ((va cam) OR (va cao)) tuc xa truong doi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ty nang ((x hoi) OR (o hoi)). hieu ((va cam) or (va cao)) tuc xa truong doi cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sanh ty nang ((x hoi) OR (o hoi)). hieu ((va cam) or (va cao)) tuc xa truong doi cua tre*.
