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