Pfupiso
A reranker can improve ordering within that set, but cannot add a relevant document that retrieval missed or verify a generated answer.
Kudzika Kwakadzika
A retrieval pipeline may use a fast retriever to select candidates and a reranker to score the smaller set. Nogueira and Cho describe BERT passage reranking for MS MARCO; later work explores language-model reranking. Reranking changes candidate order, not candidate membership. In retrieval-augmented generation, a reranker cannot recover documents absent from the retrieved pool and does not establish that generated claims are supported.
Kuitwa muNyika yeChokwadi
A first-stage retriever returns candidates, and a cross-encoder scores each query-document pair before final ranking.
A reranker can move a relevant candidate higher when the retriever returned it but ranked it poorly.
A listwise language-model reranker compares candidate passages under a specific prompt and candidate budget.
Evaluate candidate recall separately from final rank quality and generated-claim support.
Ramangwana Rekudzoreredza Reranking
Select candidate count and ranking model for the task, then measure retrieval coverage, ranking quality, latency and answer grounding separately. Compare against a first-stage baseline on held-out queries. The cited sources support specific experiments, not a guarantee that reranking reduces hallucinations in every RAG system.

Chii chinonzi Retrieval Reranking?
Retrieval reranking reorders a candidate set returned by a first-stage retriever. A reranker can improve ordering within that set, but cannot add a relevant document that retrieval missed or verify a generated answer.
Ndeipi basa rerenker mune pombi yekudzosera?
Reranking ndiyo nhanho yechipiri: inonyatso kurodha vavhoti iyo inokurumidza kudzorera inodzoka, ichigonesa iko kumusoro.

Nekuti mubvunzo negwaro rega rega rinofanirwa kugadziridzwa pamwechete, haugone kufanoverengera mavheta egwaro, saka ma-encoder anomhanya chete padiki diki rakaseti.
Chii chinoita nhanho yekutanga retriever inowanzo gadziridza?
Iyo inodzoreredza inokanda yakafara, mambure anokurumidza kuwedzera kurangarira; reranker inobva yarodza precision padziva iroro.
How can a reranker affect a RAG candidate set, and what can it not guarantee?
A reranker scores and reorders only the candidates supplied to it. It cannot recover an omitted document, guarantee relevance scores are correct, or verify claims generated from the resulting passages.
