# Vector Search Comparison Project

This repository demonstrates a simple integration with **Qdrant** and provides a markdown table comparing three popular search and vector store services: **Tavily**, **Qdrant**, and **Pinecone**.

## Features

- **Qdrant Integration**  
  A lightweight wrapper (`src/qdrantIntegration.js`) that allows you to:
  - Create and delete collections
  - Upsert points (vectors + payload)
  - Perform similarity search

- **Markdown Comparison**  
  The `comparison.md` file contains a side‑by‑side table highlighting key differences and use cases for each service.

## Getting Started

1. **Clone the repository**

   ```bash
   git clone https://git.brojs.ru/kuzakhmetovartur/povtornyy-ekzamen-2-sravnitelnyy-obzor-3.git
   cd povtornyy-ekzamen-2-sravnitelnyy-obzor-3
   ```

2. **Install dependencies**

   ```bash
   npm install
   ```

3. **Set up environment variables**

   Create a `.env` file or export the following variables in your shell:

   ```bash
   export QDRANT_URL="https://your-qdrant-instance.com"
   export QDRANT_API_KEY="your_api_key"   # optional if your instance is public
   ```

4. **Use the Qdrant client**

   ```js
   const QdrantClient = require('./src/qdrantIntegration');

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

   async function demo() {
     await client.createCollection('demo', { size: 1536, distance: 'Cosine' });
     await client.upsertPoints('demo', [
       { id: 1, vector: Array(1536).fill(0.1), payload: { title: 'Example' } },
     ]);
     const results = await client.searchPoints('demo', Array(1536).fill(0.1));
     console.log(results);
   }

   demo().catch(console.error);
   ```

## Documentation
