  Astrophysical transient events like Gamma Ray Bursts (GRBs) have always been
promising candidates for multi-messenger astronomy, with electromagnetic and
gravitational wave signals having already been observed in GRBs such as GRB
170817A. The neutrino signatures of these bursts have been long-awaited as
well, with many models predicting different spectra. Most of these searches
have been in the hundreds of GeV to PeV range. However, as different models
indicate a possible lower energy neutrino signal, we intend to expand this
search to the lowest limits of IceCube (0.5-5 GeV) as well. With the plan to
look at more transient events, we present the result of the first IceCube
search for < 5 GeV astrophysical neutrinos emitted from a GRB, for GRB 221009A;
the brightest GRB ever observed. Furthermore, we present plans to improve the
observations of < 5 GeV neutrinos in IceCube, with which we plan to probe more
transient events in the future. These improvements include the addition of
direction reconstruction at these energies, and optimization of the noise
rejection. With these improvements, GRB 221009A is just the start of the
low-energy neutrino search from transient events with IceCube.
