The standard approach is to use the cross-encoder only to rerank the dozens of candidates returned by retrieval, forming a two-stage pipeline of "coarse recall + fine ranking".

UnverifiedReranking uses a cross-encoder to score query-document pairs one by one, with accuracy far higher than vector similarity but at higher computational cost, so fine ranking is done only on the small number of candidates after coarse ranking, forming a two-stage architecture of coarse ranking plus fine ranking.76% similarUnverifiedReranking uses a Cross-Encoder model to score candidate documents retrieved in the initial retrieval pairwise, then fine-ranks the Top-K to feed into the LLM.75% similarUnverified重排阶段通常对10-50条候选文档进行精排，能够捕捉双编码器遗漏的细微语义关联从而提升检索相关性72% similarVerifiedReranking is typically implemented using cross-encoders, which concatenate the query and candidate documents before feeding them in together; it usually reranks only the Top-50 to Top-100 candidates and finally selects Top-3 to Top-5 to pass to the generative model.71% similarUnverifiedReranking typically uses a CrossEncoder architecture that concatenates the query with candidate chunks for relevance scoring, and has become a standard coarse-ranking + fine-ranking two-stage architecture in industrial-grade RAG systems.70% similar
