• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chau tinh)) - hanh tang cua truong ((phuong dan) OR (huong dan)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chau tinh)) - hanh tang cua truong ((phuong dan) OR (huong dan)) toan cau".
