• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ha ve giai ((((van hoang) OR (((xuan hoang) OR (luan hoan))))) OR (tuan hoang)) minh.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ha ve giai ((((van hoang) or (((xuan hoang) OR (luan hoan))))) or (tuan hoang)) minh".
