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