• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach va nang xa hoi. hieu va cam xuc va ((((hanh di) OR (danh du))) OR (hang di)) cua tre.
• Adding a wildcard symbol may retrieve word variants: thu sach va nang xa hoi. hieu va cam xuc va ((((hanh di) or (danh du))) or (hang di)) cua tre*.
