Water Cherenkov Detector Array (WCDA), a part of Large High Altitude Air Shower Observa-
tory(LHAASO), is a very sensitive gamma source detector in hundreds GeV to dozens TeV due
to its effectvie gamma-proton discriminating capability. Triggered data is always preserved for
long term, which makes long time analysis for gamma-ray bursts (GRBs) possible. Based on
LHAASO-WCDA triggerd data when LHAASO-WCDA full arrays begins working, we searched
GRB signal using location and corresponding time extracted from GCN website if GRB bursts
in view from March 5, 2021 to Febrary 1, 2023 manually. Alert automatic analysis program
is deployed since Febrary 1, 2023, which will give analysis results in 2 days with little manual
particapation. Trial number is considered to avoiding misjudging. In this contribution we will
introduce searching strategy, alert automatic analysis workflow and present the total searching
results.
