• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly nang ((ma hoi) or (ma hoa)). hieu ve ((cam duc) OR (pham duc)) va hanh thai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly nang ((ma hoi) OR (ma hoa)). hieu ve ((cam duc) OR (pham duc)) va hanh thai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang ((ma hoi) or (ma hoa)). hieu ve ((cam duc) OR (pham duc)) va hanh thai cua triet*".
