• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach thu hang xa hoi. lieu va dau tuc van hanh di ((cuu tre) OR (((cua tre) OR (cua triet))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach thu hang xa hoi. lieu va dau tuc van hanh di ((cuu tre) or (((cua tre) OR (cua triet))))*".
