• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky mang may hoa. hieu ((ve cam) OR (ve chat)) ((xuc va) OR (duc va)) dinh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky mang may hoa. hieu ((ve cam) or (ve chat)) ((xuc va) OR (duc va)) dinh vi cua te*".
