• If you are trying to use Boolean operators, they must be ALL CAPS: (( vu sach cha me nguoi dao thong tin ) OR ( tu cac ca vien gioi trong thuong tinh ))~.
• Adding a wildcard symbol may retrieve word variants: (( vu sach cha me nguoi dao thong tin ) or ( tu cac ca vien gioi trong thuong tinh ))*.
