RAG that respects the filter

9 Mar 2026

Most wrong citations we see are not embedding problems. They are filters applied after a wide search, or not applied at all.

Put the tenant and the source collection in the query. If the policy changed on Tuesday, filter the updated-at field instead of hoping the model notices the date in the chunk.

Rerank the survivors. Do not rerank a list that still contains another customer’s text.
