The authors present preliminary results on the search for the top quark in p{bar p} collisions at {radical}s = 1.8 TeV by the D0 collaboration at the Fermilab Tevatron. The results are based on an integrated luminosity of 13.5 pb{sup {minus}1} of data collected by the D0 detector during the 1992-3 Tevatron collider run. They have searched for Standard Model t{bar t} decays into the dilepton decay modes ee + X, e{mu} + X and {mu}{mu} + X. No significant signal is observed for top quark production in these channels. They find one candidate event in the e{mu} + X channel and no events in the other two channels with an estimated non-top background of 0.76 {+-} 0.16 events.
