• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) or (((hoi tieu) OR (hoc tieu)))) lang - manh trung cua nhung cong manh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) or (((hoi tieu) OR (hoc tieu)))) lang - manh trung cua nhung cong manh toan cau*.
