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