• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien anh - ((canh doanh) OR (hanh doanh)) luan dung cong van ((ban nha) OR (ban thanh)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien anh - ((canh doanh) OR (hanh doanh)) luan dung cong van ((ban nha) or (ban thanh))".
• Adding a wildcard symbol may retrieve word variants: hoc hien anh - ((canh doanh) OR (hanh doanh)) luan dung cong van ((ban nha) or (ban thanh))*.
