• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (te sach)) ky nang xa hoi. hieu ve cam ((xuc va) OR (tuc va)) hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (te sach)) ky nang xa hoi. hieu ve cam ((xuc va) or (tuc va)) hanh vi cuu tre*.
