• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chieu xanh)) - thanh ((trang va) OR (tran van)) nhung cong trinh toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chieu xanh)) - thanh ((trang va) or (tran van)) nhung cong trinh toan tap*".
