We report on a search for the process $p\overline{p}\ensuremath{\rightarrow}\ensuremath{\gamma}+W/Z$ with $W/Z\ensuremath{\rightarrow}q\overline{q}$ in events containing two jets and a photon at the center-of-mass energy $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$, using $184\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected by the CDF II detector. A neural network event selection has been developed to optimize the rejection of the large QCD production background; it is shown that this method gives a significant improvement in both signal-to-noise ratio and signal sensitivity, as compared with an event selection based on conventional cuts. An upper limit is presented for the $\ensuremath{\gamma}+W/Z$ production cross section with the $W$ and $Z$ decaying hadronically.
