Antfly: Distributed Search Engine with Hybrid Search and RAG Capabilities

Summary

Antfly is a distributed search engine built on etcd's raft library that combines full-text search (BM25), vector similarity, and graph traversal over multimodal data including text, images, audio, and video. The system automatically generates embeddings, chunking, and graph edges as data is written, with built-in RAG (retrieval-augmented generation) agents that tie everything together. The project includes a dashboard called Antfarm for search, RAG, knowledge graphs, embeddings, and reranking capabilities.
