• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang ((mai hoi) OR (lai hoi)). hieu hien ((cap nuoc) OR (cam xuc)) van anh di cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang ((mai hoi) OR (lai hoi)). hieu hien ((cap nuoc) or (cam xuc)) van anh di cua viet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang ((mai hoi) OR (lai hoi)). hieu hien ((cap nuoc) or (cam xuc)) van anh di cua viet*.
