• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ky dang) OR (ky danh)) cay phoi. hieu ((ve cam) OR (ve cham)) duc ba lang chai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ky dang) OR (ky danh)) cay phoi. hieu ((ve cam) or (ve cham)) duc ba lang chai cua tre*".
