The search for a signal from neutrino oscillations is the most sensitive way to address the issue of whether neutrinos have a finite mass. The NOMAD experiment at CERN was designed for a nt appearance search in the cosmologically-relevant region of the parameter space. The original approach of NOMAD, entirely based on kinematic criteria for signal/background discrimination, required a fine-grained detector as well as specific reconstruction and analysis algorithms. Results obtained from the full NOMAD data set, corresponding to about 1.3M nm charged current interactions, are discussed together with the techniques used for data analysis.
