• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach y)) hang dau hoa. hieu ve cam cuc ban thanh tai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach y)) hang dau hoa. hieu ve cam cuc ban thanh tai ((cua tre) or (cuu tre))".
