• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) ((sang ma) OR (sang tao)) hoi. hieu he nam thu xac danh sai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) ((sang ma) or (sang tao)) hoi. hieu he nam thu xac danh sai cua viet*".
