• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ((ma hoi) OR (mai hoi)). ((hieu ve) OR (hieu va)) nam mua ban thanh lai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ((ma hoi) OR (mai hoi)). ((hieu ve) or (hieu va)) nam mua ban thanh lai cua triet*".
