What it does

• Hybrid search. full-text (BM25), dense vectors (RaBitQ-compressed with SPFresh-style updates), and sparse vectors (SPLADE), fused with reciprocal rank or relative score fusion in one query
• Full-text search. Lucene-style segments with highlighting, geo, regex, wildcard, and fuzzy queries, plus English and ten Snowball stemmer languages
• RAG agents. built-in retrieval-augmented generation with streaming, multi-turn chat, tool calling (graph traversal, plus web search through an Exa connection), confidence scoring, and TOON document rendering to cut prompt tokens
• Query-builder agent. turns a natural-language question into a structured Antfly query
• Graph indexes. automatic relationship extraction and graph traversal over your data
