• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sach - hanh trang cua thong cong ((tan than) OR (tan thanh)) cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sach - hanh trang cua thong cong ((tan than) OR (tan thanh)) cap*.
