• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (chao chu)) xanh - canh tranh cua thong ((cong dan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (chao chu)) xanh - canh tranh cua thong ((cong dan) OR (cong san)) toan cau*.
