We present results from searches for the top quark in ppBAR collisions at the Fermilab Tevatron Collider. The data sample was collected during 1988-89 with the Collider Detector at Fermilab and has an integrated luminosity of 4.1 pb-1. Our previous search for e-mu final states for ttBAR --> evb-mu-vbBAR decays has been extended to include the ee and mu-mu-channels. In addition, we have searched in each event with a high-transverse-momentum lepton accompanied by hadron jets for a low-transverse-momentum muon as a tag of a bottom quark in ttBAR --> lvbqqBARbBAR decays. A lower limit on the top-quark mass of 91 GeV/c2 is obtained at the 95% confidence level, assuming standard model decays.
