• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky tang) OR (kho tang)) ma hoa. hieu ve cam ((xuc va) OR (tuc va)) phan lap cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky tang) OR (kho tang)) ma hoa. hieu ve cam ((xuc va) or (tuc va)) phan lap cua te*".
