The community member is asking how to store indices in a VectorStore so they can build a RecursiveRetriever after loading it from persistent storage. They are finding it difficult to populate the node_dict parameter when creating the RecursiveRetriever instance.
A community member responds that the indices cannot be stored in a vector store unless they are embedded. They suggest the community member could serialize or pickle the indices, or use a docstore instead.
How can I store the indices in a VectorStore such that I will be able to build a RecursiveRetriever after loading it from a persistent storage? Currently I am finding it difficult to populate the node_dict parameter while creating the instance of RecursiveRetriever
