• If you are trying to use Boolean operators, they must be ALL CAPS: ho thiet tach - hanh ((tang cua) OR (tang luan)) ((nhung huong) OR (nhung phuong)) van van cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho thiet tach - hanh ((tang cua) OR (tang luan)) ((nhung huong) or (nhung phuong)) van van cau".
