Semantic Ranking in Azure AI Search | How Cross-Encoders Improve RAG Retrieval

✨ Unlock better RAG retrieval by adding Semantic Ranking on top of your Hybrid Search pipeline using Azure AI Search.

Most teams stop at vectors + BM25… but cross-encoders can take your relevance to a whole new level.

What you’ll discover: 🔥
📌 Bi-Encoders vs Cross-Encoders - why they behave differently and when each one shines
📌 L1 vs L2 retrieval phases inside Azure AI Search and how reranking reshapes your results
📌 How answers and captions are generated and why they matter for RAG quality
📌 A real C# example showing how to enable Semantic Ranking, boosted scoring, and reranker profiles
