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