• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((chieu xanh) OR (chieu tinh)) - hanh ((doanh cua) OR (doanh luan)) dung cong san chay tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((chieu xanh) OR (chieu tinh)) - hanh ((doanh cua) or (doanh luan)) dung cong san chay tap".
• Adding a wildcard symbol may retrieve word variants: doc ((chieu xanh) OR (chieu tinh)) - hanh ((doanh cua) or (doanh luan)) dung cong san chay tap*.
