• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. thien van cau duc va danh vi ((((cua triet) OR (va trien))) OR (ca tren)).
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. thien van cau duc va danh vi ((((cua triet) or (va trien))) or (ca tren))*.
