How do you search just one customer’s records?

Pinecone documents a namespace per tenant. A namespace is a named group inside an index. Have the app check who is signed in and select the allowed namespace on the server. Use filters for finer choices such as a document type, and confirm the returned records belong to the allowed collection.

What should you price and what should you keep?

Pinecone’s plan table separates storage, reads and writes. If you use a service to create vectors or write an answer, check those charges separately. Verify backup and restore on your plan. Keep the original documents, access labels and the model and settings you used to produce vectors so you can build the index again.

Which group should the app search for a fictional reader?

On paper, draw a customer help folder and a staff-only folder with two similar titles.

Map the access
Connect the customer account to its allowed namespace.
Check the result
Give the customer one useful public answer and leave the staff passage out of the search result.
