### How can I search and count all induced subgraphs in a directed graph with edge labels?

Hello all,

I can extract all induced subgraphs and count them in a graph. My question is how I can search and count all induced subgraphs in a labeled graph (a graph with edge labels)? In documentation of g.subgraph() and g.subgraph_search_count() is mentioned that these functions should work on labeled graphs as well. but it does not work. Here is an example:

sage: s=DiGraph() sage: s.add_vertex(0) sage: s.add_vertex(1) sage: s.add_edge(0,1,label="a") sage: s.plot(color_by_label=true)

sage: g.subgraph_search_count(s) 2

While it should return 1 not 2.
