• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) nang xa hoi. hieu gia than duc ((van hanh) OR (ban hanh)) vi cua triet.
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sach y)) nang xa hoi. hieu gia than duc ((van hanh) or (ban hanh)) vi cua triet*.
