Build Your Own AI-Powered Search Engine with SWIRL

In the rapidly evolving landscape of search technology, AI-powered search engines like Perplexity AI have emerged as game-changers. These systems go beyond traditional keyword matching to provide contextually relevant results and AI-generated summaries. This article explores how to build a similar system using SWIRL, an open-source framework that combines the power of large language models with flexible search capabilities.

Understanding AI-Powered Search

Traditional search engines like Google rely primarily on keyword matching and link analysis. Modern AI-powered search engines, however, leverage large language models (LLMs) to:

• Understand natural language queries
• Process and analyze search results
• Generate coherent summaries
• Provide contextual responses with citations

SWIRL: An Open-Source Alternative

SWIRL (Semantic Web Information Retrieval Layer) is an open-source framework that allows developers to build Perplexity-like search experiences. It combines traditional search capabilities with AI-powered features, making it an excellent foundation for building advanced search applications.

Key Features

1. Natural Language Processing
2. Multi-source search capabilities
3. AI-powered summarization
4. Result re-ranking
5. Source citation
6. Docker-based deployment

Setting Up Your Own Instance

Prerequisites

• Docker and Docker Compose
• OpenAI API key
• Basic understanding of containerization

Step-by-Step Implementation

1. Initial Setup

# Download the Docker configuration
curl https://raw.githubusercontent.com/swirlai/swirl-search/main/docker-compose.yaml -o docker-compose.yaml

# Set environment variables
export MSAL_CB_PORT=8000
export MSAL_HOST=localhost
export OPENAI_API_KEY='your-OpenAI-API-key'

2. Launch the Container

# For MacOS/Linux
docker-compose pull && docker-compose up

# For Windows
(PowerShell) docker compose up

3. Configure Search Sources

• Access admin panel at http://localhost:8000
• Default credentials: admin/password
• Configure search providers and connectors

Extending Functionality

Adding Custom Data Sources

class CustomDataConnector:
     def __init__(self, config):
       self.config = config
   async def search(self, query):
      # Implement custom search logic
      results = await self._fetch_results(query)
      return self._process_results(results)

Implementing Custom Re-ranking

class CustomReRanker:
     def __init__(self, model):
        self.model = model
     def rerank(self, results, query):
        scores = self._calculate_relevance(results, query)
        return sorted(results, key=lambda x: scores[x.id], reverse=True)
