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