This paper reports the result of a search for the standard model
Higgs boson in events containing four reconstructed jets associated
with quarks. For masses below 135GeV/c2, Higgs boson decays to
bottom-antibottom quark pairs are dominant and result primarily in two
hadronic jets. An additional two jets can be produced in the hadronic
decay of a W or Z boson produced in association with the Higgs boson,
or from the incoming quarks that produced the Higgs boson through the
vector-boson fusion process. The search is performed using a sample of
s**(1/2) = 1.96 TeV proton-antiproton collisions corresponding to an
integrated luminosity of 9.45 fb-1 recorded by the CDF II detector. The
data are in agreement with the background model and 95% credibility
level upper limits on Higgs boson production are set as a function of the
Higgs boson mass. The median expected (observed) limit for a 125GeV/c2
Higgs boson is 11.0 (9.0) times the predicted standard model rate.
