• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - canh tranh cua thuong thong ((((dan toan) OR (xuan toan))) OR (dan chan)) tap~.
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - canh tranh cua thuong thong ((((dan toan) or (xuan toan))) or (dan chan)) tap*.
