• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((((chieu xanh) OR (chieu tinh))) OR (vien nganh)) - thanh trung cua dong trong san van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((((chieu xanh) OR (chieu tinh))) or (vien nganh)) - thanh trung cua dong trong san van ban*".
