🛠️ Troubleshooting

Google API Blocked

Symptom: "Blocked by Google" warnings

Solutions:

1. Reduce query rate in code
2. Use proxy rotation
3. Fallback search engines will auto-activate

No Results Found

Check:

• Internet connection
• API credentials validity
• Try different search engines
• Verify dork syntax

CAPTCHA Warnings

This means:

• Search engine detected automation
• Scanner will pause affected engine
• Other engines continue working
