• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ty hang)) xa hoi. thien van ((nam mua) OR (nam cua)) van thanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) OR (ty hang)) xa hoi. thien van ((nam mua) or (nam cua)) van thanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty nang) OR (ty hang)) xa hoi. thien van ((nam mua) or (nam cua)) van thanh vi cua tre*.
