• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chi) OR (theo nghi)) lang - hanh doanh cua ((nhung cong) OR (hang cong)) dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chi) or (theo nghi)) lang - hanh doanh cua ((nhung cong) OR (hang cong)) dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chi) or (theo nghi)) lang - hanh doanh cua ((nhung cong) OR (hang cong)) dan toan cao*.
