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