New solar twins and siblings in the ELODIE and SOPHIE archives

Solar twins were searched in the ELODIE and SOPHIE archives by matching spectra to solar ones and applying a minimum distance criterion. New very close solar twins never reported before were found. Solar siblings were also searched by looking at stars having the same abundances than the Sun. For that
purpose a purely differential method was applied on a line by line basis.
