# SurrealDB

## English Abstract

SurrealDB is a multi-model database (document, graph, vector, full-text, time-series) with SurrealQL — suited for hybrid RAG including RRF.

## Quick Answer (EN)

SurrealDB is a multi-model database (document, graph, vector, full-text, time-series) with SurrealQL — suited for hybrid RAG including RRF.

## Key Takeaways (EN)

- One engine instead of separate vector + graph + search stores.
- Hybrid retrieval via HNSW vectors and BM25 with RRF.
- Powers the Modern Stack knowledge graph (Hetzner DE).

## English Summary

SurrealDB consolidates heterogeneous data models and hybrid search in one Rust engine. Modern Stack runs the growing_brands knowledge graph namespace on shared Surreal infrastructure in Germany.


## Quick Answer

**SurrealDB:** Multi-Model-Datenbank (Dokument, Graph, Vektor, Volltext, Zeitreihe) mit SurrealQL — geeignet für hybride [RAG](/glossar/rag)-Suche inklusive Reciprocal Rank Fusion.

## Key Takeaways

- Eine Engine statt separater Vector-/Graph-/Search-Stacks.
- Hybrid-Retrieval: HNSW-Vektoren + BM25, fusioniert per RRF.
- Bei Modern Stack: Knowledge Graph auf Hetzner DE.

## Definition und Kontext

[SurrealDB](/glossar/surrealdb) eliminiert Systemgrenzen zwischen Ähnlichkeits-, Keyword- und Beziehungssuche. Verwandt: [Knowledge Graph](/themen/knowledge-graph), [Webarchitektur im KI-Zeitalter](/themen/webarchitektur-ki-zeitalter), [Convex](/glossar/convex).

## FAQ

### Was ist SurrealDB?

SurrealDB ist eine Multi-Model-Datenbank: Dokumente, Graphen, Vektoren und Volltext in einer Engine, abfragbar mit SurrealQL.

### Warum SurrealDB für GEO und Knowledge Graph?

Weil thematische Entities, Relationen und semantische Suche ohne drei Spezialdatenbanken auskommen — inkl. hybrider Suche (Vektor + Keyword).
