• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky lang xa hoi. hieu ca nhan ((luc ban) OR (duc ban)) hanh vi ((va trien) OR (ve triet)).
• Adding a wildcard symbol may retrieve word variants: thu sac ky lang xa hoi. hieu ca nhan ((luc ban) or (duc ban)) hanh vi ((va trien) or (ve triet))*.
