  We report a search for astronomical neutrinos in the energy region from
several GeV to TeV in the direction of the blazar TXS0506+056 using the
Super-Kamiokande detector following the detection of a 100 TeV neutrino from
the same location by the IceCube collaboration. Using Super-Kamiokande neutrino
data across several data samples observed from April 1996 to February 2018 we
have searched for both a total excess above known backgrounds across the entire
period as well as localized excesses on smaller time scales in that interval.
No significant excess nor significant variation in the observed event rate are
found in the blazar direction. Upper limits are placed on the electron and muon
neutrino fluxes at 90\% confidence level as $6.03 \times 10^{-7}$ and $4.52
\times 10^{-7}$ to $9.26 \times 10^{-10}$ [${\rm erg}/{\rm cm}^2/{\rm s}$],
respectively.
