• If you are trying to use Boolean operators, they must be ALL CAPS: tu cai ky nang x hoi. hieu van thanh soc ((ban hang) OR (((va dauh) OR (va dau)))) di cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu cai ky nang x hoi. hieu van thanh soc ((ban hang) or (((va dauh) or (va dau)))) di cuu tre*.
