• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang x ho. hieu va tham loc ((va danh) OR (va dinh)) dai ((cua te) OR (cua su)).
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang x ho. hieu va tham loc ((va danh) or (va dinh)) dai ((cua te) or (cua su))*.
