• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ty) OR (sach thu)) nang ((ma hoi) OR (xa hoi)). hieu vi pham chuc va hanh hai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ty) OR (sach thu)) nang ((ma hoi) or (xa hoi)). hieu vi pham chuc va hanh hai cua triet~".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ty) OR (sach thu)) nang ((ma hoi) or (xa hoi)). hieu vi pham chuc va hanh hai cua triet*.
