• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - anh dang cua bang ((((song dan) OR (cong dan))) or (song van)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - anh dang cua bang ((((song dan) OR (cong dan))) OR (song van)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - anh dang cua bang ((((song dan) OR (cong dan))) or (song van)) toan cau".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - anh dang cua bang ((((song dan) OR (cong dan))) or (song van)) toan cau*.
