• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - thanh ((((trung tuan) OR (trung thanh))) or (tran tuan)) nhung cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh ((((trung tuan) OR (trung thanh))) OR (tran tuan)) nhung cong dan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh ((((trung tuan) OR (trung thanh))) or (tran tuan)) nhung cong dan toan cau*".
