• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly nang ((ma hoa) OR (xa hoi)). hieu ((van dau) OR (phan dau)) xuc va danh de cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly nang ((ma hoa) or (xa hoi)). hieu ((van dau) OR (phan dau)) xuc va danh de cua te*".
