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