It cannot recover documents missing from that set.
Jin Dive
A two-stage retrieval system first retrieves candidates, then reranks them. Cross-encoders jointly process query and candidate text and can be computationally expensive across very large corpora; bi-encoders produce separate embeddings that support efficient initial retrieval. Listwise methods score multiple candidates together. A reranker cannot promote a document absent from the candidate set, and its score is not automatically a probability of relevance. Claims about universal accuracy gains or reduced hallucinations require task-specific evaluation. A named example is Nogueira and Cho’s Passage Re-ranking with BERT, which applies BERT to query-based passage re-ranking and reports results on TREC-CAR and MS MARCO. This example does not establish the prevalence of any architecture across all reranking systems.

Retrieve a small candidate set, then rerank it for a question.
Measure retrieval recall and reranking quality separately.
Use query-document scoring to reorder retrieved passages.
Check the cited source passages before using results in a generated answer.
Ojo iwaju ti Reranking Models
Reranking methods and model sizes continue to change. Benchmark latency and quality on the actual corpus and query set; treat product comparisons and future accuracy gains as hypotheses until measured.

What is Reranking Models?
A reranker reorders a candidate set from an initial retriever, often using a richer query-document scoring model. It cannot recover documents missing from that set.

Awọn sare retriever fetches oludije; awọn reranker ki o si tun-maaki ti kukuru akojọ lati Titari awọn julọ ti o yẹ esi si oke.
Besides MS MARCO, on which dataset did Nogueira and Cho report strong results for their BERT passage reranker?
The paper reports results on TREC-CAR as well as the MS MARCO passage retrieval task. This is a result reported for that study, not a general reranker benchmark claim.

How can a reranker affect context quality in a retrieval-augmented generation pipeline?
Reranking reorders candidates by model-estimated relevance; the candidate pool and scoring errors still limit what reaches the generator.
