## Overview

Implement semantic vector search with AgentDB for intelligent document retrieval, similarity matching, and context-aware querying. Build RAG systems, semantic search engines, and knowledge bases.

## SOP Framework: 5-Phase Semantic Search

### Phase 1: Setup Vector Database (1-2 hours)
- Initialize AgentDB
- Configure embedding model
- Setup database schema

### Phase 2: Embed Documents (1-2 hours)
- Process document corpus
- Generate embeddings
- Store vectors with metadata

### Phase 3: Build Search Index (1-2 hours)
- Create HNSW index
- Optimize search parameters
- Test retrieval accuracy

### Phase 4: Implement Query Interface (1-2 hours)
- Create REST API endpoints
- Add filtering and ranking
- Implement hybrid search

### Phase 5: Refine and Optimize (1-2 hours)
- Improve relevance
- Add re-ranking
- Performance tuning

## Quick Start

```typescript
import { AgentDB, EmbeddingModel } from 'agentdb-vector-search';

// Initialize
const db = new AgentDB({ name: 'semantic-search', dimensions: 1536 });
const embedder = new EmbeddingModel('openai/ada-002');

// Embed documents
for (const doc of documents) {
  const embedding = await embedder.embed(doc.text);
  await db.insert({
    id: doc.id,
    vector: embedding,
    metadata: { title: doc.title, content: doc.text }
  });
}

// Search
const query = 'machine learning tutorials';
const queryEmbedding = await embedder.embed(query);
const results = await db.search({
  vector: queryEmbedding,
  topK: 10,
  filter: { category: 'tech' }
});
```

## Features

- **Semantic Search**: Meaning-based retrieval
- **Hybrid Search**: Vector + keyword search
- **Filtering**: Metadata-based filtering
- **Re-ranking**: Improve result relevance
- **RAG Integration**: Context for LLMs

## Success Metrics
- [assert|neutral] Retrieval accuracy > 90% [ground:acceptance-criteria] [conf:0.90] [state:provisional]
- [assert|neutral] Query latency < 100ms [ground:acceptance-criteria] [conf:0.90] [state:provisional]
- [assert|neutral] Relevant results in top-10: > 95% [ground:acceptance-criteria] [conf:0.90] [state:provisional]
- [assert|neutral] API uptime > 99.9% [ground:acceptance-criteria] [conf:0.90] [state:provisional]

## MCP Requirements

This skill operates using AgentDB's npm package and API only. No additional MCP servers required.

All AgentDB operations are performed through:
- npm CLI: `npx agentdb@latest`
- TypeScript/JavaScript API: `import { AgentDB } from 'agentdb-vector-search'`

## Core Principles

AgentDB Semantic Vector Search operates on 3 fundamental principles for building intelligent document retrieval systems:

### Principle 1: Meaning Over Keywords

Semantic search retrieves documents based on meaning similarity rather than exact keyword matching, enabling context-aware retrieval.

In practice:
- Generate embeddings for documents using models like OpenAI ada-002 (1536 dimensions) to capture semantic meaning
- Store vectors with rich metadata (title, content, category, tags) to enable hybrid search combining semantic and keyword filters
- Search using query embeddings to find semantically similar documents even when exact keywords differ
- Implement distance metrics (cosine similarity, euclidean) to rank results by semantic relevance rather than keyword frequency

### Principle 2: Performance Through Indexing

Build HNSW indexes for 150x faster vector search compared to exhaustive search, essential for production-scale retrieval.

In practice:
- Create HNSW (Hierarchical Navigable Small World) indexes after document ingestion to enable fast approximate nearest neighbor search
- Optimize search parameters (ef_construction, M) based on accuracy vs speed tradeoffs for your use case
- Test retrieval accuracy with evaluation datasets to en
