• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (doi chieu)) sach - hanh trang quang ((trung huong) OR (trung duong)) van thang ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) sach - hanh trang quang ((trung huong) OR (trung duong)) van thang ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) sach - hanh trang quang ((trung huong) OR (trung duong)) van thang ban*".
