• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - manh tran tuan nhung ((cong san) OR (cong tac)) ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - manh tran tuan nhung ((cong san) OR (cong tac)) ((toan cau) OR (toan ban))*.
