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