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