• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung pham tong ((cong dan) OR (cong tan)) ((tranh cac) OR (thanh ca))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung pham tong ((cong dan) OR (cong tan)) ((tranh cac) or (thanh ca))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung pham tong ((cong dan) OR (cong tan)) ((tranh cac) or (thanh ca))*.
