• Performing a fuzzy search may retrieve terms with similar spellings: su ((((sach ky) OR (sach ty))) or (sac ky)) nang ma hoi. hieu ve cam tu va anh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((sach ky) OR (sach ty))) OR (sac ky)) nang ma hoi. hieu ve cam tu va anh vai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((sach ky) OR (sach ty))) or (sac ky)) nang ma hoi. hieu ve cam tu va anh vai cua triet*".
