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