  Several solar analogs have been identified in the library of high resolution
stellar spectra taken with the echelle spectrograph ELODIE. A purely
differential method has been used, based on the chi2 comparison of a large
number of G dwarf spectra to 8 spectra of the Sun, taken on the Moon and Ceres.
HD 146233 keeps its status of closest ever solar twin (Porto de Mello & da
Silva 1997). Some other spectroscopic analogs have never been studied before,
while the two planet-host stars HD095128 and HD186427 are also part of the
selection. The fundamental parameters found in the literature for these stars
show a surprising dispersion, partly due to the uncertainties which affect
them.
  We discuss the advantages and drawbacks of photometric and spectroscopic
methods to search for solar analogs and conclude that they have to be used
jointly to find real solar twins.
