• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc hien)) sach - thanh trung tuan nhung tung dan ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc hien)) sach - thanh trung tuan nhung tung dan ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc hien)) sach - thanh trung tuan nhung tung dan ((than cau) OR (than cap))*.
