• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((hop mang) OR (hop thang))) or (nhap mang)) - anh dang cua nhung cong tan tran cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((((hop mang) OR (hop thang))) or (nhap mang)) - anh dang cua nhung cong tan tran cau*.
