• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y xang xa hoi. hieu va ((cac ly) OR (mac le)) va hanh vi ((cua tre) OR (cua triet)).
• Adding a wildcard symbol may retrieve word variants: su sach y xang xa hoi. hieu va ((cac ly) or (mac le)) va hanh vi ((cua tre) or (cua triet))*.
