• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky sang ma hoa. hieu ve cham tuc va ((danh lai) or (danh sai)) ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky sang ma hoa. hieu ve cham tuc va ((danh lai) OR (danh sai)) ((cua triet) OR (va triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky sang ma hoa. hieu ve cham tuc va ((danh lai) or (danh sai)) ((cua triet) OR (va triet))*".
