• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu va cam duc va hanh vi ((((dua tren) OR (cua te))) OR (cau tren))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu va cam duc va hanh vi ((((dua tren) OR (cua te))) OR (cau tren))*.
