• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (((so sach) OR (co sach)))) y nang mai hoi. hieu va chat luc va thanh cat va triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (((so sach) OR (co sach)))) y nang mai hoi. hieu va chat luc va thanh cat va triet~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (((so sach) OR (co sach)))) y nang mai hoi. hieu va chat luc va thanh cat va triet*.
