Webstatus of the neutrino search at the Observatory using about 15 years of data. Restrictive upper bounds on the neutrino ux from di use sources and from point-like steady sources were stablished, placing strong constraints on several models of neutrino production at EeV energies and on the properties of the sources of ultra-high-energy cosmic rays.
