• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) ky ((lang xa) OR (lang van)) hoi. lieu va tham xuc ban thanh de cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (so sanh)) ky ((lang xa) OR (lang van)) hoi. lieu va tham xuc ban thanh de cua tu".
