• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang xa hoi. ((hieu cao) OR (chieu cao)) chat hoa van hanh vi ((cau tren) OR (cau theo))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang xa hoi. ((hieu cao) OR (chieu cao)) chat hoa van hanh vi ((cau tren) or (cau theo))~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky tang xa hoi. ((hieu cao) OR (chieu cao)) chat hoa van hanh vi ((cau tren) or (cau theo))*.
