• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thue nang xa hoi. ((hieu ve) OR (hieu qua)) cam xuc ((va doanh) OR (vay doanh)) van cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thue nang xa hoi. ((hieu ve) or (hieu qua)) cam xuc ((va doanh) OR (vay doanh)) van cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach thue nang xa hoi. ((hieu ve) or (hieu qua)) cam xuc ((va doanh) OR (vay doanh)) van cuu tre*.
