• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dang xa hoi. lieu ((va chat) OR (cao chat)) xuc va thanh vi ((cuu tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang xa hoi. lieu ((va chat) or (cao chat)) xuc va thanh vi ((cuu tre) OR (cau tren))".
• Adding a wildcard symbol may retrieve word variants: te sach ky dang xa hoi. lieu ((va chat) or (cao chat)) xuc va thanh vi ((cuu tre) OR (cau tren))*.
