• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((thu hoach) OR (thuat sach)) trai nghiem va hoc ) OR ( tu sach tai nghiep luan hoc ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((thu hoach) or (thuat sach)) trai nghiem va hoc ) or ( tu sach tai nghiep luan hoc ))*.
