• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((song xa) OR (((cong cua) OR (huong cua)))) hoi. hieu ve cam hoc dan hanh dai va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((song xa) or (((cong cua) OR (huong cua)))) hoi. hieu ve cam hoc dan hanh dai va triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((song xa) or (((cong cua) OR (huong cua)))) hoi. hieu ve cam hoc dan hanh dai va triet*.
