• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky nang xa hoi. hieu ve ((nam thuc) OR (tam tu)) va hanh dai ((cua tre) OR (cua te)).
• Adding a wildcard symbol may retrieve word variants: te sai ky nang xa hoi. hieu ve ((nam thuc) or (tam tu)) va hanh dai ((cua tre) or (cua te))*.
