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