Data search method, data detection method, data detection device and equipment

The embodiment of the invention provides a data search method, a data detection method, a data detection device and equipment, and the method comprises the steps: determining a first number and a second number corresponding to a false transaction condition, the false transaction condition being that at least a first number of users buy at least a second number of commodities together; generating a bipartite graph corresponding to the to-be-detected transaction data; pruning the bipartite graph according to the false transaction conditions so as to filter out user nodes, commodity nodes and edges which do not meet the false transaction conditions from the bipartite graph; and determining false transaction data existing in the to-be-detected transaction data according to the bipartite graph after pruning processing. The bipartite graph corresponding to the transaction data is pruned based on the false transaction condition by setting the false transaction condition, so that the scale of the bipartite graph can
