• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dang xay hoi. lieu va cam luc ((va hang) OR (va lang)) tri ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang xay hoi. lieu va cam luc ((va hang) or (va lang)) tri ((cua tre) OR (cua triet))".
