-python3 health_rec/manage_data.py --create <collection_name>
-OPENAI_API_KEY=$YOUR_OPENAI_API_KEY python3 health_rec/manage_data.py --load <collection_name> --data-dir /data --load-embeddings
-python3 health_rec/manage_data.py --list

+OPENAI_API_KEY=$YOUR_OPENAI_API_KEY python3 health_rec/manage_data.py load --name <collection_name> --data-dir /data --load-embeddings
+python3 health_rec/manage_data.py list
 ```
