• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu tang ((ma hoi) OR (xa hoi)). hieu vu cham duc ((va hanh) OR (va thanh)) lam chat triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach thu tang ((ma hoi) or (xa hoi)). hieu vu cham duc ((va hanh) OR (va thanh)) lam chat triet~".
• Adding a wildcard symbol may retrieve word variants: so sach thu tang ((ma hoi) or (xa hoi)). hieu vu cham duc ((va hanh) OR (va thanh)) lam chat triet*.
