• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - nhanh hang va phuong cong van ((((tan cao) OR (tan ca))) OR (tay cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - nhanh hang va phuong cong van ((((tan cao) OR (tan ca))) or (tay cao))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - nhanh hang va phuong cong van ((((tan cao) OR (tan ca))) or (tay cao))*.
