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