Search and Retrievalwith Hybrid RAG
Fusioni combines keyword search, semantic search and vector similarity into a single retrieval pipeline. Agents pull the right content from your sources and generate answers grounded in real data—not guesswork.
Hybrid Search
Combines BM25 keyword matching with dense vector retrieval. Better coverage across both precise terminology queries and open-ended natural language questions—without having to choose one or the other.
Vector Search
Uses embeddings to find content by meaning, not just words. Supports multiple embedding models—you can assign different models per collection or use case.
Multi-Modal RAG
Retrieves from text, images, PDFs and structured sources. Results are fed directly to the LLM as context, with chunking, reranking and filtering applied before answer generation.
