• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky ((mang xa) or (tang ma)) hoi. hieu ve cam ((loc van) OR (luoc van)) hanh cua chua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((mang xa) OR (tang ma)) hoi. hieu ve cam ((loc van) OR (luoc van)) hanh cua chua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((mang xa) or (tang ma)) hoi. hieu ve cam ((loc van) OR (luoc van)) hanh cua chua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((mang xa) or (tang ma)) hoi. hieu ve cam ((loc van) OR (luoc van)) hanh cua chua triet*.
