• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) nang x hoi. hieu ve ((cham duc) OR (pham duy)) va hanh mau va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) nang x hoi. hieu ve ((cham duc) or (pham duy)) va hanh mau va triet*".
