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