• If you are trying to use Boolean operators, they must be ALL CAPS: (((("tu sach duoc lam nguoi") OR ("tu sach hoc lam nguoi"))) OR ("thu sach duoc pham nguoi"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"tu sach duoc lam nguoi\") OR (\"tu sach hoc lam nguoi\"))) or (\"thu sach duoc pham nguoi\"))*".
• Removing quotes may allow a broader search: (((( tu sach duoc lam nguoi ) OR ( tu sach hoc lam nguoi ))) or ( thu sach duoc pham nguoi ))*.
