SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Surreal-vector-search enables high-performance vector search in SurrealDB 3.0, bridging vector similarity with BM25 and hybrid retrieval.

Core Features & Use Cases

HNSW index design with configurable distance metrics and quantization for memory efficiency
BM25 full-text fusion to enable hybrid retrieval combining keyword and vector signals
Production tuning guidance for Rust MCP projects, including recall, latency, and monitoring benchmarks

Quick Start

Provide a first-class hybrid vector+BM25 search example by running a query that uses a sample vector and a text query to retrieve top-k results from the memories index.

FAQPage Schema

How do I configure HNSW parameters for SurrealDB vector search?▼

To configure HNSW vector search in SurrealDB, you set the M and efConstruction parameters to balance graph connectivity and search efficiency, directly impacting recall and latency for your specific Rust MCP workload.

What is hybrid retrieval and how does BM25 fusion work with vector search?▼

Hybrid retrieval merges semantic vector similarity with BM25 full-text keyword scoring. Enabling BM25 fusion combines vector and keyword signals to improve search accuracy for queries requiring both exact matches and contextual meaning.

Does SurrealDB support quantization for memory-efficient vector search?▼

Yes, SurrealDB supports quantization for vector search. Enabling quantization compresses vector embeddings to reduce memory consumption while maintaining acceptable recall rates for large-scale semantic search and RAG pipelines.

Can I use SurrealDB for RAG retrieval in a Rust MCP project?▼

Yes, you can use SurrealDB for RAG retrieval in Rust MCP projects. It provides vector similarity search, configurable distance metrics, and hybrid BM25 fusion to build and optimize real-world retrieval pipelines.

What is the best way to benchmark recall and latency for a vector search pipeline?▼

The best way to benchmark vector search pipelines is by validating recall and latency against real-world workloads. This involves tuning HNSW parameters, selecting distance metrics, and testing hybrid BM25 fusion configurations.
