• If you are trying to use Boolean operators, they must be ALL CAPS: theo hieu quang - ((hanh doanh) OR (nhung doanh)) cua thuong ((phuong van) OR (phung van)) han tai~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo hieu quang - ((hanh doanh) or (nhung doanh)) cua thuong ((phuong van) OR (phung van)) han tai~".
• Adding a wildcard symbol may retrieve word variants: theo hieu quang - ((hanh doanh) or (nhung doanh)) cua thuong ((phuong van) OR (phung van)) han tai*.
