python scripts/search.py "EV news" --type news --time-range m --output ev_news.txt

Implementation Approach

When users request web searches:

Identify search intent:
- What type of content (web, news, images, videos)?
- How recent should results be?
- How many results are needed?
- Any filtering requirements?
Configure search parameters:
- Choose appropriate search type (--type)
- Set time range if currency matters (--time-range)
- Adjust result count (--max-results)
- Apply filters (image size, video duration, etc.)
Select output format:
- Text for quick reading
- Markdown for documentation
- JSON for further processing
Execute search:
- Run the search command
- Save to file if results need to be preserved
- Print to stdout for immediate review
Process results:
- Read saved files if needed
- Extract URLs or specific information
- Combine results from multiple searches

Quick Reference

Command structure:

python scripts/search.py "" [options]

Essential options:

-t, --type - Search type (web, news, images, videos)
-n, --max-results - Maximum results (default: 10)
--time-range - Time filter (d, w, m, y)
-r, --region - Region code (e.g., us-en, uk-en)
--safe-search - Safe search level (on, moderate, off)
-f, --format - Output format (text, markdown, json)
-o, --output - Save to file

Image-specific options:

--video-resolution - Resolution filter (high, standard)

Get full help:

python scripts/search.py --help

Best Practices

Be specific - Use clear, specific search queries for better results
Use time filters - Apply --time-range for current information
Adjust result count - Start with 10-20 results, increase if needed
Save important searches - Use --output to preserve results
Choose appropriate type - Use news search for current events, web for general info
Use JSON for automation - JSON format is easiest to parse programmatically
Respect usage - Don't hammer the API with rapid repeated searches

Troubleshooting

Common issues:

"Missing required dependency": Run pip install duckduckgo-search
No results found: Try broader search terms or remove time filters
Timeout errors: The search service may be temporarily unavailable; retry after a moment
Rate limiting: Space out searches if making many requests
Unexpected results: DuckDuckGo's results may differ from Google; try refining the query

Limitations:

Results quality depends on DuckDuckGo's index and algorithms
No advanced search operators (unlike Google's site:, filetype:, etc.)
Image and video searches may have fewer results than web search
No control over result ranking or relevance scoring
Some specialized searches may work better on dedicated search engines

Advanced Use Cases

Combining Multiple Searches

Gather comprehensive information by combining search types:

# Web overview
python scripts/search.py "topic" --max-results 15 --output topic_web.txt

# Recent news
python scripts/search.py "topic" --type news --time-range w --output topic_news.txt

# Images
python scripts/search.py "topic" --type images --max-results 20 --output topic_images.txt

Programmatic Processing

Use JSON output for automated processing:

python scripts/search.py "research topic" --format json --output results.json
# Then process with another script
python analyze_results.py results.json

Building a Knowledge Base

Create searchable documentation from web results:

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