Using 1.16 × 106 BB events collected at the γ(4S) resonance by the CLEO Collaboration at the Cornell Electron Storage Ring (CESR), we have searched for decays of B mesons to exclusive two-body hadronic final states including a Ds+ or a Ds*+ meson. We obtain the 90% confidence level upper limit β (B → Ds(*)+π- + Ds*+p- + Ds(*)+π0 + Ds(*)+η + Ds(*)+p0 + Ds(*)+(ω) × β(Ds+ → φπ+) < 1.8 × 10-5. We have also searched for the W-exchange decays, B0 → Ds(*)-K(*)+.
