• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (((bo sach) OR (hoc sach)))) ky dang xa hoi. hieu van dao thuc dat khanh ve cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (((bo sach) or (hoc sach)))) ky dang xa hoi. hieu van dao thuc dat khanh ve cua tre*.
