• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((chieu sach) OR (chiet tach))) OR (chieu sang)) - hanh ban cua dung phuong manh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu sach) OR (chiet tach))) or (chieu sang)) - hanh ban cua dung phuong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu sach) OR (chiet tach))) or (chieu sang)) - hanh ban cua dung phuong manh toan cau*.
