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