• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh ((trong he) OR (trong hiep)) thong cong van ((thanh cau) OR (thanh mau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((trong he) or (trong hiep)) thong cong van ((thanh cau) OR (thanh mau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((trong he) or (trong hiep)) thong cong van ((thanh cau) OR (thanh mau))*.
