• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (thiet yeu)) sach - ((nhanh dung) OR (nhanh dong)) ca thuong dong san toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (thiet yeu)) sach - ((nhanh dung) OR (nhanh dong)) ca thuong dong san toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thiet yeu)) sach - ((nhanh dung) OR (nhanh dong)) ca thuong dong san toan ban*".
