• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - ((canh trinh) OR (hanh trinh)) vat thong cong ((dan thanh) OR (dang thanh)) lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu xanh - ((canh trinh) or (hanh trinh)) vat thong cong ((dan thanh) OR (dang thanh)) lap~".
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - ((canh trinh) or (hanh trinh)) vat thong cong ((dan thanh) OR (dang thanh)) lap*.
