  We present a search for the Standard Model Higgs boson produced in
association with a Z or a W boson, using data collected with the CDF II
detector at the Tevatron accelerator. A scenario where the Z decays into
neutrinos or charged leptons originating from the W-decay escape detection and
the Higgs decays into a $b\overline{b}$ pair is considered. Therefore the
expected signature is large missing transverse energy ($\etmiss$), no isolated
leptons, and two $b$-jets. We present the preliminary results in this search
using 1.7$fb^{-1}$ of data collected by CDF and the work on future improvements
to increase the sensitivity of the analysis.
