• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky nang ma hoi. hieu ((ve cac) OR (va cac)) tuc va danh lai chau viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ky nang ma hoi. hieu ((ve cac) OR (va cac)) tuc va danh lai chau viet*".
