The challenge
Imagine an internal knowledge product that needs to search both exact records and semantically related documents. Every employee sees only sources they are entitled to access.
A thoughtful approach
Store document metadata and ownership alongside embeddings, constrain all retrieval by verified permissions, and evaluate retrieval quality. Log document updates and deletions so stale embeddings cannot linger unnoticed.
What this story demonstrates
This is a conceptual example, not a published implementation or customer testimonial. The pgvector capability it references is planned for the private alpha.
