We report on a search for supersymmetry using the D\O detector. The 1994-1996 data sample of $$\sqrt{s}=1.8$$ TeV $$p\bar{p}$$ collisions was analyzed for events containing two leptons ($$e$$ or $$\mu$$), two or more jets, and missing transverse energy. Assuming the minimal supergravity model, with $$A_0=0$$ and $$\mu<0$$, various thresholds were employed to optimize the search. No events were found beyond expectation from background. We set a lower limit at the 95% C.L. of 255 GeV/$c^2$ for equal mass squarks and gluinos for $$\tan{\beta}=2$$, and present exclusion contours in the $$(m_0,m_{1/2})$$ plane for $$\tan{\beta}=2$$--6.
