We present results from searches for the top quark {ital p{bar p}} 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{sup {minus}1}. Our previous search for {ital e}{mu} final states for {ital t{bar t}}{r arrow}{ital e}{nu}{ital b} {mu}{nu}{ital {bar b}} decays has been extended to include the {ital 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 {ital t{bar t}}{r arrow}{ital l}{nu}{ital bq{bar q}{bar b}} decays. A lower limit on the top-quark mass of 91 GeV/{ital c}{sup 2} is obtained at the 95% confidence level, assuming standard model decays.
