• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach lo ((hang x) OR (hoang xa)) hoi. hieu van chat luc va dinh van ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach lo ((hang x) or (hoang xa)) hoi. hieu van chat luc va dinh van ((cua tre) OR (cua triet))*".
