Help to create a POC

Hi,

I was wondering whether you could help with a few quick questions in order for me to create a POC:

a) What is the difference between openSearchVCEmbedding.py and vector_embedding.py. Is vector_embedding.py used?
b). In openSearchVCEmbedding.py in the add_documents function, the file_name parameter is the jsonl file with the database schema, correct?
3) I don't see the add_documents function called anywhere?

Thanks a ton!
