Metadata Filtering

Restricting vector search to documents whose attributes match conditions such as date, source or access level.

Definition

Metadata filters improve relevance and enforce access control in RAG by excluding documents a user should not see or that are out of scope.

Example

Filter retrieval to department = 'finance' and year >= 2025.

Exam tip

Use metadata filtering to enforce document-level permissions in RAG.
