• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doc hieu)) xanh - hanh trang cua ((nhung cong) OR (thong cong)) van toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doc hieu)) xanh - hanh trang cua ((nhung cong) OR (thong cong)) van toan cao".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doc hieu)) xanh - hanh trang cua ((nhung cong) OR (thong cong)) van toan cao*.
