• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khach)) ty ((nang x) OR (long ha)) hoi. lieu va phan duoc ban hang doi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu khach)) ty ((nang x) or (long ha)) hoi. lieu va phan duoc ban hang doi cua te~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (vu khach)) ty ((nang x) or (long ha)) hoi. lieu va phan duoc ban hang doi cua te*.
