If i want to find multiple subgraphs in a target graph that are isomorphic to the query graph, how to modify the code?

I have adjusted the code, but my goal is to find all the subgraphs in the target graph that are isomorphic to the query graph. Now I can only find one. I would like to ask you if you want to query multiple subgraphs. How to modify that recursive function, if I can get your advice, I would be very grateful.
