• If you are trying to use Boolean operators, they must be ALL CAPS: toc hieu manh - ((hanh doanh) OR (chinh doanh)) ((ca thuong) OR (cao thuong)) cong tac toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc hieu manh - ((hanh doanh) or (chinh doanh)) ((ca thuong) OR (cao thuong)) cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: toc hieu manh - ((hanh doanh) or (chinh doanh)) ((ca thuong) OR (cao thuong)) cong tac toan cau*.
