• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((((mang xa) OR (dang xay))) OR (nang ma)) hoi. hieu ve cam thuc dan thanh doi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((((mang xa) OR (dang xay))) OR (nang ma)) hoi. hieu ve cam thuc dan thanh doi cua triet*.
