• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach dai nang x hoi. hieu ve ((cham tuc) OR (pham thuc)) va danh di ((cua viet) OR (ca viet))~.
• Adding a wildcard symbol may retrieve word variants: toc sach dai nang x hoi. hieu ve ((cham tuc) or (pham thuc)) va danh di ((cua viet) or (ca viet))*.
