• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. ((((thien van) OR (thi lien))) OR (lieu va)) cau tuc va hanh vi cua tre.
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang xa hoi. ((((thien van) or (thi lien))) or (lieu va)) cau tuc va hanh vi cua tre*.
