Preliminary results from a search for the production of an associated lightest chargino, W{sub 1}, and second lightest neutralino, Z{sub 2}, pair with the D0 detector at Fermilab`s pp collider with {radical}s = 1.8 TeV are presented. Based on approximately 85 pb{sup -1} of data collected during the 1993-1995 Tevatron Runs we set a 95% C.L. upper limit on the chargino-neutralino cross section times branching fraction to any trileptonic final state ranging from 0.91 pb to 0.19 pb for wino masses ranging from 45 GeV/c{sup 2} to 96 GeV/c{sup 2}.
