• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chu manh)) - hanh hang ca ((nhung cong) OR (hang cong)) tan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chu manh)) - hanh hang ca ((nhung cong) or (hang cong)) tan toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chu manh)) - hanh hang ca ((nhung cong) or (hang cong)) tan toan cau*.
