  A search for the standard model Higgs boson in the \bbbar decay channel has
been carried out with the CMS detector at the LHC collider. The searched
production modes are the associated VH production, the VBF production and the
production in association with top quark pairs (ttH). The analyses are based on
pp collision data collected at centre-of-mass energies of 7 and 8 TeV,
corresponding to integrated luminosities of 5 fb$^{-1}$ and 20 fb$^{-1}$,
respectively. The strategy and results of the searches are reported.
