• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chu xanh) OR (chua xang)) - ((tinh bang) OR (anh dang)) luan nhung cong tan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) OR (chua xang)) - ((tinh bang) or (anh dang)) luan nhung cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) OR (chua xang)) - ((tinh bang) or (anh dang)) luan nhung cong tan toan cao*.
