• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach thu ((nang xa) OR (nang ma)) hoi. thi van cam xuc va doanh van ((cua triet) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach thu ((nang xa) OR (nang ma)) hoi. thi van cam xuc va doanh van ((cua triet) or (cua te))*".
