• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((hieu manh) OR (chau tinh)) - ((hanh doanh) OR (doanh doanh)) cua thong cong san phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((hieu manh) or (chau tinh)) - ((hanh doanh) OR (doanh doanh)) cua thong cong san phan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((hieu manh) or (chau tinh)) - ((hanh doanh) OR (doanh doanh)) cua thong cong san phan cau*.
