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