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