• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu ((((ve cai) OR (ve cau))) OR (ve cac)) xuc va danh di cua tre.
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu ((((ve cai) or (ve cau))) or (ve cac)) xuc va danh di cua tre*.
