A search for B{sub s}{sup 0}-{ovr B}{sub s}{sup 0} oscillations is performed in a sample of B{sub s}{sup 0} semileptonic decays collected using dilepton triggers at the Tevatron Collider during 1992-1995. The B{sub s}{sup 0} is reconstructed using phiv meson-lepton correlations; its initial flavor is determined with the second lepton in the event. From a signal of 1068 with a B{sub s}{sup 0} purity of 61%, we obtain a limit on the B{sub 2}{sup 0}-{ovr B}{sub s}{sup 0} oscillation frequency of {Delta}m{sub s}>5.8 ps{sup -1} at 95% confidence level.
