• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (((vu khach) OR (vu khanh)))) ky van xay hoi. hieu ve cam duc va thanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (((vu khach) OR (vu khanh)))) ky van xay hoi. hieu ve cam duc va thanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (((vu khach) OR (vu khanh)))) ky van xay hoi. hieu ve cam duc va thanh vi cua te*.
