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