Hi im having trouble deleting a file

When you execute index.delete_ref_doc(doc._id) it does not work

Added for extra info so i can explain myself better

There are two problems in this flow. 1. The IndexDocumentSummary expects a doc_id, if you look at the previous steps the argument is the node_id

In step 1 the ref_doc_info is recovered form self.docstore.get_ref_doc_info(ref_doc_id). In my case (Can some one explain me why) each document has 2 nodes, but only one is used for the document summary so only one is in the self._index_sturct.node_id_to_summary_id dictionary

Which this causes is an error on step 3

I see that this steps are programmed by @jerryjliu0 and @Logan M . If any of you could help me understand this better maybe I can open a PR
