• If you are trying to use Boolean operators, they must be ALL CAPS: theo hieu qua - ((hanh doanh) OR (chinh doanh)) luan thuong thong quan ((han tai) OR (dung tai)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo hieu qua - ((hanh doanh) OR (chinh doanh)) luan thuong thong quan ((han tai) or (dung tai))".
• Adding a wildcard symbol may retrieve word variants: theo hieu qua - ((hanh doanh) OR (chinh doanh)) luan thuong thong quan ((han tai) or (dung tai))*.
