• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. lieu va ((((cac xuc) OR (cac nuoc))) OR (cam xuc)) va dau thi huu tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. lieu va ((((cac xuc) or (cac nuoc))) or (cam xuc)) va dau thi huu tre*.
