Introducing Search Toolkit | Mistral AI

This post introduces the Search Toolkit, a new framework for building production search pipelines for AI applications. It integrates ingestion, retrieval (BM25, dense, hybrid), and evaluation (recall, precision, MRR, NDCG) into a unified system. Key technical contributions include a common configuration interface across modules, support for custom document formats and preprocessing via adapters, and built-in evaluation metrics to measure retriever performance independently. The post also highlights its use in enterprise search, RAG, and domain-specific retrieval, and its integration with Connectors for agentic workflows.
