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