Stroring the index in a format other than json

[jozamm]

Hi all,

I am using LayoutPDFReader to read multiple documents

doc = pdf_loader.read_pdf(pdf) documents.append(doc)

Than create an index using the following code

for doc in documents: for chunk in doc.chunks(): index.insert(Document(text=chunk.to_context_text(), extra_info={}))

Now I need to store a perisistant copy of the index. Currently when using

index.storage_context.persist("Test")

the index is stored as a json file.

Since one cannot use the from_documents call (I get an error AttributeError: 'Document' object has no attribute 'get_doc_id') ,
how can I save the database in SQL format or any other format.

Thanks
