• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach kem) OR (sach ty)) nang x hoi. lieu va cham ((quoc ban) OR (quoc lan)) anh d cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach kem) or (sach ty)) nang x hoi. lieu va cham ((quoc ban) OR (quoc lan)) anh d cua triet*".
