• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (((sach ty) OR (sach tu)))) nang co hoi. hieu va am thuc va danh vai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) or (((sach ty) OR (sach tu)))) nang co hoi. hieu va am thuc va danh vai cua triet~".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) or (((sach ty) OR (sach tu)))) nang co hoi. hieu va am thuc va danh vai cua triet*.
