• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu tinh) OR (chieu sach)) - hanh trung tuan nhung huong dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu tinh) or (chieu sach)) - hanh trung tuan nhung huong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu tinh) or (chieu sach)) - hanh trung tuan nhung huong dan ((toan cau) OR (toan ban))*.
