• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty danh dai moi. hieu van cam loc va danh va ((((chu tri) OR (cu tri))) OR (chu thi))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty danh dai moi. hieu van cam loc va danh va ((((chu tri) OR (cu tri))) or (chu thi))*".
