• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ((thue nano) or (truc nano)) x hoi. thien van cam xuc van dinh cu va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ((thue nano) OR (truc nano)) x hoi. thien van cam xuc van dinh cu va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ((thue nano) or (truc nano)) x hoi. thien van cam xuc van dinh cu va triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ((thue nano) or (truc nano)) x hoi. thien van cam xuc van dinh cu va triet*.
