For the search the full data set recorded by the Belle experiment of $711 \\, \\mathrm{fb}^{-1}$ integrated luminosity near the $\\Upsilon (4S)$ resonance is used. Signal candidates are reconstructed for photon energies $E_{\\gamma}$ larger than $1 \\, \\mathrm{GeV}$ using a novel multivariate tagging algorithm.
