• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky nang ((ma hoa) OR (mai hoi)). hieu van nam tu va hanh vi ((cua te) OR (su triet)).
• Adding a wildcard symbol may retrieve word variants: thu san ky nang ((ma hoa) or (mai hoi)). hieu van nam tu va hanh vi ((cua te) or (su triet))*.
