• -C or --collection-name: Specify the name of the collection to query.
• --query: Enter your query within double quotes.
• --chain-type: Choose the chain method (e.g., stuff, refine, map_reduce, map_rerank).

Delete a Collection

Delete an existing collection using the delete subcommand:

./ragtool.py delete -C my_collection --force

• -C or --collection-name: Specify the name of the collection to delete.
• --force: Use this flag to forcefully delete the collection without confirmation.

Check and Enable pgvector Extension
