If you wanted to do some sort of entity resoltution. What would be the best way to delete and add entities back into the graph? Would it be defining a custom retriever to retrieve nodes you want to combine then coming up with a way to delete and upsert those nodes?
Like we have different user uploading different files would it make sense to store all user data in one graph and then parse on something or is there a way to easily scope to specific graphs or sub-graphs etc?
Also one more thing? Do you know why page_label is refering to the document(chunk) index instead of the page_number when using simple directory reader for loading documents from PDFs?
