• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu manh - ((anh bang) OR (anh hoang)) luan ((phung cong) OR (hong cuong)) tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - ((anh bang) OR (anh hoang)) luan ((phung cong) or (hong cuong)) tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - ((anh bang) OR (anh hoang)) luan ((phung cong) or (hong cuong)) tan toan cau*.
