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