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