SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables fast semantic search by leveraging AgentDB's vector database to store document embeddings and perform high-precision similarity queries, empowering knowledge bases, RAG workflows, and intelligent document retrieval.

Core Features & Use Cases

  • Vector storage with embeddings: store documents with numeric representations for fast similarity, retrieval, and ranking.
  • High-performance search: uses HNSW indexing and quantization options for sub-millisecond responses on large corpora.
  • Hybrid/contextual search: combine vector similarity with metadata filters for precise results; supports retrieval augmented generation (RAG) workflows.
  • Use Case: build a knowledge base that quickly finds relevant documents and extracts context for QA or summarization tasks.

Quick Start

Install and configure AgentDB, initialize a vector store, and perform a sample semantic search:

  • Initialize: npx agentdb@latest init ./vectors.db --dimension 768 --preset small
  • Store a document embedding: (illustrative example) npx agentdb@latest insert ./vectors.db --embedding "[0.1,0.2,...]" --text "Example document" --metadata '{"category":"sample"}'
  • Query: npx agentdb@latest query ./vectors.db "[0.1,0.2,0.3]" -k 5

FAQPage Schema
How do I implement semantic search for a Node.js knowledge base?▼

Semantic search in a Node.js knowledge base is implemented by storing document embeddings in a vector database and performing HNSW-indexed similarity queries. This Skill automates that process using AgentDB to enable fast, intelligent document retrieval across large corpora.

How does HNSW indexing improve vector search performance for large corpora?▼

HNSW indexing improves vector search performance by organizing embeddings into a hierarchical graph structure, enabling sub-millisecond similarity queries. This Skill leverages HNSW within AgentDB to maintain high retrieval speeds even when scaling up document collections.

Can I combine metadata filters with vector similarity search in a RAG workflow?▼

Yes, you can combine metadata filters with vector similarity search to perform hybrid contextual retrieval. This Skill supports metadata-assisted hybrid search, allowing you to refine embedding-based results for precise context extraction in RAG workflows.

What is the best way to store document embeddings for retrieval in Node.js?▼

The best way to store document embeddings in Node.js is using a dedicated vector database that supports high-dimensional numeric representations. This Skill uses AgentDB to store embeddings alongside text and metadata for fast similarity ranking and retrieval.

Does AgentDB support memory-efficient vector storage for large datasets?▼

AgentDB supports memory-efficient vector storage through optional quantization features. This Skill utilizes quantization within AgentDB to reduce the memory footprint of stored embeddings while maintaining high-precision similarity search capabilities.
