• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sanh)) ty nang ma hoi. lieu ((va cam) OR (va cham)) luc va thanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sanh)) ty nang ma hoi. lieu ((va cam) OR (va cham)) luc va thanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sanh)) ty nang ma hoi. lieu ((va cam) OR (va cham)) luc va thanh vi cua tre*.
