• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - hanh trang qua dung cong san ((thang cap) OR (((thong cap) OR (trung cap))))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh trang qua dung cong san ((thang cap) or (((thong cap) or (trung cap))))*.
