I have a csv file containing multiple fields and from that I am only adding the first_name & last_name and making unique id using uuid to the vectorstore. Now I want to add one more field from my csv to this vector only, kindly help to implement same. This is my code which I wrote inorder to make the vector. def proc_f(df_chunk, faiss_module, chunk_idx): faiss_mod = FAISSModule() df_chunk.fillna("NA", inplace=True) df_chunk['vectortext'] = df_chunk['first_name'] + df_chunk['last_name'] df_chunk['_id'] = df_chunk.apply( lambda x: base64.b64encode(str.encode(x['vectortext'])).decode(), axis=1) df_chunk['doctext'] = [ Document(page_content=vectext, metadata={'id': _id}) for vectext, _id in zip(df_chunk['vectortext'], df_chunk['_id']) ] documents = df_chunk['doctext'].values.tolist() faiss_mod.add_documents(documents) faiss_mod.save_index(f".//faiss_chunk_{chunk_idx}.index") print(f"Chunk {chunk_idx} processed and FAISS index saved.") return df_chunk Is it possible to update the current vectorstore or I need to rerun the whole process?
