• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky dang xay hoi. hieu viec lam thuc dan hang di ((cua triet) OR (((cuu tre) OR (cau treo)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky dang xay hoi. hieu viec lam thuc dan hang di ((cua triet) or (((cuu tre) OR (cau treo))))".
