Output Format

Search Result

{
    "success": True,
    "query": "search query",
    "engine": "baidu+playwright",
    "num_results": 5,
    "results": [
        {
            "title": "Result title",
            "href": "https://...",
            "body": "Snippet content"
        }
    ],
    "message": "Search completed"
}

Deep Search Result

{
    "success": True,
    "query": "search query",

Execution

type: script script_path: scripts/web_search.py entry_point: main dependencies:

• uv>=0.1.0
• requests>=2.28.0
• baidusearch>=1.0.3
• crawl4ai>=0.8.0
• playwright>=1.40.0

Search Strategy

1. Primary: baidusearch library (fastest, no browser)
2. Secondary: Playwright + Baidu (most reliable, bypasses anti-bot)
3. Tertiary: DuckDuckGo (privacy-focused)
4. Fallback: Bing (international)

Notes

1. First Run: Playwright will download Chromium browser on first use (~100MB)
2. Rate Limiting: Be mindful of search frequency to avoid temporary blocks
3. Network: Requires internet connection
4. Results: May vary based on search engine algorithms and location

Error Handling

• Returns {"success": False, "message": "..."} on errors
• Automatically retries with fallback engines
• Graceful degradation when optional dependencies are missing
