• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - hanh trang cua tong ((((cong tap) OR (cong tan))) OR (cong san)) toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - hanh trang cua tong ((((cong tap) OR (cong tan))) or (cong san)) toan ban*".
