• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sang) OR (nhieu tang))) OR (hieu lang)) - thanh trung cua thuong cong van tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu sang) OR (nhieu tang))) or (hieu lang)) - thanh trung cua thuong cong van tuan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu sang) OR (nhieu tang))) or (hieu lang)) - thanh trung cua thuong cong van tuan cau*.
