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