Using data collected on the Υ(4S) resonance and the nearby continuum by the CLEO detector at the Cornell Electron Storage Ring, we have searched for the semileptonic decay of B mesons to ep̅ inclusive final states. We obtain an upper limit for bc decays of B(Bp̅ e-ν̅ eX)<5.9×10-4. For the bu decay, we find an upper limit of B(B-pp̅ e-ν̅ e)<1.2×10-3 based on a V-A model, while a phase space model gives an upper limit of B(B-pp̅ e-ν̅ e)<5.2×10-3. All upper limits are measured at the 90% confidence level.
