Page Title Here URL: https://example.com/page Brief description of the page content... 2. Another Result URL: https://example.com/another Another description... ``` ### Markdown Format ```markdown ## 1. Page Title Here **URL:** https://example.com/page Brief description of the page content... ## 2. Another Result **URL:** https://example.com/another Another description... ``` ### JSON Format ```json [ { "title": "Page Title Here", "href": "https://example.com/page", "body": "Brief description of the page content..." }, { "title": "Another Result", "href": "https://example.com/another", "body": "Another description..." } ] ``` ## Common Usage Patterns ### Research on a Topic Gather comprehensive information about a subject: ```bash # Get overview from web python scripts/search.py "machine learning basics" --max-results 15 --output ml_web.txt # Get recent news python scripts/search.py "machine learning" --type news --time-range m --output ml_news.txt # Find tutorial videos python scripts/search.py "machine learning tutorial" --type videos --max-results 10 --output ml_videos.txt ``` ### Current Events Monitoring Track news on specific topics: ```bash python scripts/search.py "climate summit" --type news --time-range d --format markdown --output daily_climate_news.md ``` ### Finding Visual Resources Search for images with specific criteria: ```bash python scripts/search.py "data visualization examples" --type images --image-type photo --image-size Large --max-results 25 --output viz_images.txt ``` ### Fact-Checking Verify information with recent sources: ```bash python scripts/search.py "specific claim to verify" --time-range w --max-results 20 ``` ### Academic Research Find resources on scholarly topics: ```bash python scripts/search.py "quantum entanglement research" --time-range y --max-results 30 --output quantum_research.txt ``` ### Market Research Gather information about products or companies: ```bash python scripts/search.py "electric vehicle market 2025" --max-results 20 --format markdown --output ev_market.md python scripts/search.py "EV news" --type news --time-range m --output ev_news.txt ``` ## Implementation Approach When users request web searches: 1. **Identify search intent**: - What type of content (web, news, images, videos)? - How recent should results be? - How many results are needed? - Any filtering requirements? 2. **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.) 3. **Select output format**: - Text for quick reading - Markdown for documentation - JSON for further processing 4. **Execute search**: - Run the search command - Save to file if results need to be preserved - Print to stdout for immediate review 5. **Process results**: - Read saved files if needed - Extract URLs or specific information - Combine results from multiple searches ## Quick Reference **Command structure:** ```bash 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:** - `--image-size` - Size filter (Small, Medium, Large, Wallpaper) - `--image-color` - Color filter - `--image-type` - Type filter (photo, clipart, gif, transparent, line) - `--image-layout` - Layout filter (Square, Tall, Wide) **Video-specific options:** - `--video-duration` - Duration filter (short, medium, long) - `--video-resolution` - Resolution filter (high, standard) **Get full help:** ```bash python scripts/search.py --help ``` ## Best Practices 1. **Be specific** - Use clear, specific search queries for better results 2. **Use time filters** - Apply `--time-range` for current information 3. **Adjust result count** - Start with 10-20 results, increase if needed 4. **Save important searches** - Use `--output` to preserve results 5. **Choose appropriate type** - Use news search for current events, web for general info 6. **Use JSON for automation** - JSON format is easiest to parse programmatically 7. **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: ```bash # 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: ```bash 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: ```bash # 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 ``` ## Resources ### scripts/search.py The main search tool implementing DuckDuckGo search functionality.
