• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang ((ha hoi) OR (hoa hoi)). hieu qua cam xuc ((ban thanh) OR (va dan)) di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang ((ha hoi) OR (hoa hoi)). hieu qua cam xuc ((ban thanh) or (va dan)) di cua triet*".
