• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (te sach)) ky nang ma hoi. hieu ve cac ((xuc va) OR (duc va)) thanh via cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (te sach)) ky nang ma hoi. hieu ve cac ((xuc va) OR (duc va)) thanh via cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (te sach)) ky nang ma hoi. hieu ve cac ((xuc va) OR (duc va)) thanh via cua tre*.
