SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

AgentDB Vector Search enables fast, scalable semantic search by leveraging AgentDB's vector store for document retrieval and relevance ranking across large datasets.

Core Features & Use Cases

  • Fast vector storage and retrieval with HNSW indexing
  • Hybrid search combining vector similarity and metadata filtering
  • MCP server integration for Claude Code and CLI tooling

Quick Start

Initialize a small AgentDB vector store and perform a sample semantic query to verify setup.

Frequently Asked Questions about AgentDB Vector Search

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add semantic vector search to my RAG pipeline for fast document retrieval?▼

Semantic vector search for RAG pipelines is enabled by storing document embeddings in AgentDB and retrieving them via HNSW indexing. This approach provides fast similarity ranking and context-aware document understanding across large knowledge bases.

Does AgentDB vector search support hybrid queries combining metadata filtering with embedding similarity?▼

Yes, hybrid search in AgentDB combines vector similarity with metadata filtering to refine results. This allows you to apply structural constraints alongside semantic matching, improving relevance ranking for complex research archives.

Can I integrate vector search and retrieval with Claude Code using an MCP server?▼

Vector search integrates with Claude Code and CLI tooling through MCP server support. This allows Claude to query the AgentDB vector store directly, enabling intelligent retrieval within AI-assisted workflows.

What are the requirements to set up AgentDB for scalable similarity search?▼

Scalable similarity search requires Node.js 18+ and AgentDB v1.0.7 or higher, running standalone or via agentic-flow. The system supports HNSW indexing and quantization to maintain fast retrieval speeds as dataset size grows.

Why use HNSW indexing and quantization for large-scale document retrieval?▼

HNSW indexing and quantization optimize large-scale document retrieval by reducing vector storage footprint and accelerating similarity search. This ensures fast query performance and context-aware ranking across extensive research archives.

When should I use AgentDB for vector search instead of other vector database solutions?▼

Use AgentDB for vector search when you need fast, scalable semantic retrieval integrated directly into Node.js environments or MCP-compatible AI workflows. It is ideal for RAG pipelines requiring hybrid metadata filtering and HNSW indexing without external database overhead.
