SearXNG Search

Web search integration using SearXNG meta-search engine. SearXNG aggregates results from multiple search engines (Google, Bing, DuckDuckGo, etc.) without tracking or ads.

Quick Start

# Search
python scripts/search.py "quantum computing latest research"

# With specific engine
python scripts/search.py "weather in Tokyo" --engines duckduckgo

# News search
python scripts/search.py "AI breakthroughs 2024" --category news

Python API

from searxng import SearXNGClient

# Initialize
client = SearXNGClient()

# Search
results = client.search("quantum computing")

# Access results
for result in results["results"]:
    print(f"{result['title']}: {result['url']}")

# Search with options
results = client.search(
    query="AI safety",

Features

Multiple Engine Aggregation

Results from 70+ search engines including:

• Google, Bing, DuckDuckGo

• Academic (arXiv, PubMed)

Privacy

• No tracking
• No ads
• Self-hostable

Rate Limiting

Built-in rate limiting to respect SearXNG instances:

# Automatic delay between requests
client = SearXNGClient(rate_limit=1.0)  # 1 second between calls

Response Format

{
  "query": "quantum computing",
  "number_of_results": 10,
  "results": [
    {
      "title": "Quantum Computing - Wikipedia",
      "url": "https://en.wikipedia.org/wiki/Quantum_computing",
      "content": "Quantum computing is a type of computation...",
      "engine": "wikipedia",
      "score": 1.0
    }
  ],
  "suggestions": ["quantum computing explained", "quantum computing applications"],
  "infobox": {}  // Knowledge panel if available
}

Testing

# Run search tests
python tests/test_search.py

Troubleshooting

"Connection refused"

# Check if SearXNG instance is reachable
curl https://your-searx-instance/healthz

"No results"

• Try different engines: --engines google,duckduckgo
• Check category: --category general
• Verify instance isn't rate-limiting you

"Rate limited"

• Add delay between requests
• Use different SearXNG instance
• Self-host your own instance

Self-Hosting

Deploy your own SearXNG:

# Docker
docker run -d --name searxng -p 8080:8080 \
  -v searxng-config:/etc/searxng \
  searxng/searxng:latest

# Then update config/searxng.yaml
base_url: "http://localhost:8080"

Public Instances

Popular public SearXNG instances:

• https://searx.be
• https://search.sapti.me
• https://searx.tiekoetter.com
• https://search.bus-hit.me

Note: Public instances may have rate limits. For heavy use, self-host.

Requirements

• Python 3.8+
• requests library
• SearXNG instance (public or self-hosted)
