• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((hieu manh) OR (chieu tinh)) - manh cuong cua hang huong dan ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: doi ((hieu manh) or (chieu tinh)) - manh cuong cua hang huong dan ((toan cau) or (toan tap))*.
