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