Qdrant Vector Database Skill

Quick Start Workflow

When working with Qdrant:

1. Check if Qdrant is configured

   • Look for QDRANT_URL and QDRANT_API_KEY in .env
   • For local: http://localhost:6333
   • For cloud: https://xxx.qdrant.io

2. For collection creation

   • Define vector size (1536 for OpenAI ada-002)
   • Choose distance metric (Cosine for semantic similarity)
   • Set up HNSW parameters for performance

3. For content ingestion

   • Chunk text into 800-character segments with 200-char overlap
   • Generate embeddings with OpenAI text-embedding-ada-002
   • Upsert vectors with metadata (chapter, section, file path)

4. For semantic search

   • Convert user query to embedding
   • Search with score threshold (>= 0.7 for relevance)
   • Return top 5 results with metadata

Standard Patterns

Client Setup

import { QdrantClient } from '@qdrant/js-client';

export const qdrant = new QdrantClient({
  url: process.env.QDRANT_URL,
  apiKey: process.env.QDRANT_API_KEY,
});

Collection Configuration

await qdrant.createCollection('textbook_chunks', {
  vectors: {
    size: 1536, // OpenAI ada-002
    distance: 'Cosine',
  },
  hnsw_config: {
    m: 16,
    ef_construct: 100,
  },
});

Best Practices

For Physical AI textbook RAG:

• Collection name: textbook_chunks
• Vector size: 1536 (OpenAI ada-002 embeddings)
• Chunk size: 800 characters with 200 overlap
• Score threshold: 0.7 minimum for relevance
• Batch size: 100 vectors per upsert operation
• Metadata: Always include chapter, section, file path
