• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua nang) OR (chuc nang)) - ((nhanh huong) OR (nhanh chuong)) cua bang cong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua nang) or (chuc nang)) - ((nhanh huong) OR (nhanh chuong)) cua bang cong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: theo ((chua nang) or (chuc nang)) - ((nhanh huong) OR (nhanh chuong)) cua bang cong dan toan cao*.
