• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu tinh)) - canh ((trinh toan) OR (trinh quan)) nhung cong doan phan tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu tinh)) - canh ((trinh toan) or (trinh quan)) nhung cong doan phan tu".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu tinh)) - canh ((trinh toan) or (trinh quan)) nhung cong doan phan tu*.
