• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach y)) nang xa hoi. hieu ((va cam) OR (ve cham)) thuc va hanh va huu tre.
• Adding a wildcard symbol may retrieve word variants: su ((sach ty) or (sach y)) nang xa hoi. hieu ((va cam) or (ve cham)) thuc va hanh va huu tre*.
