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