• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) nang hoa hoi. hieu qua cam ((lo anh) OR (ly anh)) xuan vai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach y)) nang hoa hoi. hieu qua cam ((lo anh) OR (ly anh)) xuan vai cua triet*".
