Definition
A retrieval strategy in RAG pipelines that leverages structured metadata categories to narrow the vector search space, ensuring the LLM receives context that is both semantically relevant and aligned with specific attributes like date range, document source, or classification level.
In RAG, this is metadata-constrained retrieval, not just a sidebar of checkboxes in an e-commerce UI.
"A multi-layered sieve that filters out all pebbles (documents) except for those that are specifically blue, square, and from the 'River' category before checking for weight (semantic similarity)."
