Considering RAG reranking

3.2Standard

Vector search returns many candidates and the best evidence is not near the top.

Improve the candidate order before generation.

Choose two appropriate practices.

Hint 1: Focus on the requirement

Improve ordering among retrieved candidates, but continue to check recall, authority, freshness, and access.

Hint 2: Key terms

Review candidate retrieval and reranking.

Reranking: Reordering retrieved candidates with a relevance model or additional constraints.
Candidate retrieval: Selecting a manageable set of items from a larger corpus for downstream evaluation.
Recall: The share of relevant items present in the candidate set or returned results.
Access control: Rules determining which principal may retrieve or use a resource.
