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