• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) OR (vu bach)) tu nang ((xa hoi) or (mai hoi)). thien van cam duc va hanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) tu nang ((xa hoi) OR (mai hoi)). thien van cam duc va hanh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu bach)) tu nang ((xa hoi) or (mai hoi)). thien van cam duc va hanh di cua triet*".
