• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu manh) OR (chu han)) - hanh tang cua nhung cong tan ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu manh) OR (chu han)) - hanh tang cua nhung cong tan ((toan cau) or (toan ban))*.
