• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chau) OR (o chau)) tinh - thanh trung quan dung cong san ((toan cau) or (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chau) OR (o chau)) tinh - thanh trung quan dung cong san ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chau) OR (o chau)) tinh - thanh trung quan dung cong san ((toan cau) or (toan cao))*".
