We report a search for (Formula presented) oscillations using a sample of (Formula presented) hadronic (Formula presented) decays collected by the SLD experiment. The analysis takes advantage of the electron beam polarization as well as information from the hemisphere opposite that of the reconstructed B decay to tag the B production flavor. The excellent resolution provided by the pixel CCD vertex detector is exploited to cleanly reconstruct both B and cascade D decay vertices, and tag the B decay flavor from the charge difference between them. We exclude the following values of the (Formula presented) oscillation frequency: (Formula presented) and (Formula presented) at the (Formula presented) confidence level.
