Graph explore API - Get documents related to graph edges

Hi! I'm creating a Graph using my Elasticsearch index and I can get my graph data using Graph Explore API. The returned data through API is the same as the documentation explains. But I'd like to know if there is any way to don't just get the vertices and relations of my fields, but get the documents related to that fields.

For example: A vértice has 20 related documents, I'd like to get those 20 documets through API.

If you are referring to the venn diagram with the overlap, then it's simply doing a a search, matching both nodes. Each node is simply a field and a value which translates into the corresponding match_phrase query
