• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach ty) OR (sach tu)) ((xang xa) OR (ang xa)) hoi. hieu va cac tuc xa thanh hoa cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach ty) OR (sach tu)) ((xang xa) or (ang xa)) hoi. hieu va cac tuc xa thanh hoa cua viet".
