• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ly hang cua hoi. hieu van nam xuc va hang di ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ly hang cua hoi. hieu van nam xuc va hang di ((cua triet) OR (su triet))*".
