• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chua) OR (ho chua)) xang - ((hanh mang) OR (anh nang)) cua hang cong trinh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chua) OR (ho chua)) xang - ((hanh mang) or (anh nang)) cua hang cong trinh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chua) OR (ho chua)) xang - ((hanh mang) or (anh nang)) cua hang cong trinh toan cao*.
