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