• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (nhieu tang)) - hanh trinh ((va duong) OR (va tuong)) vuong manh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (nhieu tang)) - hanh trinh ((va duong) OR (va tuong)) vuong manh toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (nhieu tang)) - hanh trinh ((va duong) OR (va tuong)) vuong manh toan cau*.
