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