• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) or (cuon sach)) ky nang cao hoi. thien van hau luc va danh di ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (cuon sach)) ky nang cao hoi. thien van hau luc va danh di ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (cuon sach)) ky nang cao hoi. thien van hau luc va danh di ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (cuon sach)) ky nang cao hoi. thien van hau luc va danh di ((cua tre) OR (cua triet))*.
