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