• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang xa hoi. hieu vien cap nuoc giao thanh vi ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) ky nang xa hoi. hieu vien cap nuoc giao thanh vi ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) ky nang xa hoi. hieu vien cap nuoc giao thanh vi ((cua te) or (cua tu))*.
