• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((song xa) OR (dong cua)) hoi. hieu van dau ((xuc van) OR (duc van)) anh lai va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((song xa) or (dong cua)) hoi. hieu van dau ((xuc van) OR (duc van)) anh lai va triet".
