• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y lang xa hoi. hieu va cam ((((xuc ban) OR (quoc ban))) OR (duc van)) danh hai cua triet.
• Adding a wildcard symbol may retrieve word variants: thu sach y lang xa hoi. hieu va cam ((((xuc ban) or (quoc ban))) or (duc van)) danh hai cua triet*.
