Subgraph Matching (2.2.16)

**Table 1** Parameter description
Parameter	Mandatory	Description	Type	Value Range
edges	Yes	Edge set of the subgraph to be matched. The vertex ID must be of the size_t type.	String	The value is in standard CSV format. The start and end vertices of an edge are separated by a comma (,), and edges are separated by a newline character (\n). For example, 1,2\n2,3.
vertices	Yes	Label of each vertex on the subgraph to be matched.	String	The value is in standard CSV format. Vertices and their labels are separated by commas (,), and labels are separated by newline characters (\n). For example, 1,BP\n2,FBP\n3,CP.
directed	No	Whether to consider the direction of the graph	Boolean	The value can be true or false. The default value is true.
n	No	Maximum number of subgraphs to be searched for	Integer	The value range is [1,100000]. The default value is 100.
batch_number	No	Number of queries processed in batches each time	Integer	The value range is [1,1000000]. The default value is 10000.
statistics	No	Whether to display the number of all subgraphs that meet the conditions	Boolean	The value can be true or false. The default value is false.

**Table 2** response_data parameter description
Parameter	Mandatory	Type	Description
subgraphs	Yes	List	Subgraphs with the same pattern of the pattern_graph. The value is in the [[subgraph1],[subgraph2], ...] format. Each subgraph is in the [vertex1,vertex2, ...] format, where vertex is of the string type. The vertices of each subgraph correspond to those of pattern_graph.
pattern_graph	Yes	List	Graph pattern. The value is in the [vertex1,vertex2, ...] format, where vertex is of the string type.
subgraph_number	No	Integer	Number of matched graphs. When statistics is set to true, the total number of graphs that meet query conditions is displayed.
