Retrieve a connected subgraph of nodes where the label includes the specified `node_label`. Retrieve a connected subgraph of nodes where the label includes the specified `node_label`.
Maximum number of nodes is constrained by the environment variable `MAX_GRAPH_NODES` (default: 1000).
When reducing the number of nodes, the prioritization criteria are as follows: When reducing the number of nodes, the prioritization criteria are as follows:
1. Label matching nodes take precedence 1. Hops(path) to the staring node take precedence
2. Followed by nodes directly connected to the matching nodes 2. Followed by the degree of the nodes
3. Finally, the degree of the nodes
Args: Args:
node_label: Label of the starting node node_label: Label of the starting node
max_depth: Maximum depth of the subgraph max_depth: Maximum depth of the subgraph, Defaults to 3
inclusive: Do an inclusive search if true max_nodes: Maxiumu nodes to return
Returns: Returns:
KnowledgeGraph: Complete connected subgraph for specified node KnowledgeGraph: Complete connected subgraph for specified node
