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