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