Web Search

Overview

Search the web using DuckDuckGo's API to find information across web pages, news articles, images, and videos. Returns results in multiple formats (text, markdown, JSON) with filtering options for time range, region, and safe search.

When to Use This Skill

Use this skill when users request:

• Web searches for information or resources
• Finding current or recent information online
• Looking up news articles about specific topics
• Searching for images by description or topic
• Finding videos on specific subjects
• Research requiring current web data
• Fact-checking or verification using web sources
• Gathering URLs and resources on a topic

Prerequisites

OpenSquilla declares the required duckduckgo-search Python package as a runtime dependency. For source checkouts, run the normal project dependency sync before invoking this bundled skill. The library provides a simple Python interface to DuckDuckGo's search API without requiring API keys or authentication.

Core Capabilities

1. Basic Web Search

Search for web pages and information:

python {baseDir}/scripts/search.py "<query>"

Example:

python {baseDir}/scripts/search.py "python asyncio tutorial"

Returns the top 10 web results with titles, URLs, and descriptions in a clean text format.

2. Limiting Results

Control the number of results returned:

python {baseDir}/scripts/search.py "<query>" --max-results <N>

Example:

python {baseDir}/scripts/search.py "machine learning frameworks" --max-results 20

Useful for:

• Getting more comprehensive results (increase limit)
• Quick lookups with fewer results (decrease limit)
• Balancing detail vs. processing time

3. Time Range Filtering

Filter results by recency:

python {baseDir}/scripts/search.py "<query>" --time-range <d|w|m|y>

Time range options:

• d - Past day
• w - Past week
• m - Past month
• y - Past year

Example:

python {baseDir}/scripts/search.py "artificial intelligence news" --time-range w

Great for:

• Finding recent news or updates
• Filtering out outdated content
• Tracking recent developments

4. News Search

Search specifically for news articles:

python {baseDir}/scripts/search.py "<query>" --type news

Example:

python {baseDir}/scripts/search.py "climate change" --type news --time-range w --max-results 15

News results include:

• Article title
• Source publication
• Publication date
• URL
• Article summary/description

5. Image Search

8. Safe Search Control

Control safe search filtering:

python {baseDir}/scripts/search.py "<query>" --safe-search <on|moderate|off>

Options:

• on - Strict filtering
• moderate - Balanced filtering (default)
• off - No filtering

Example:

python {baseDir}/scripts/search.py "medical information" --safe-search on

9. Output Formats

Choose how results are formatted:

Text format (default):

python {baseDir}/scripts/search.py "quantum computing"

Clean, readable plain text with numbered results.

Markdown format:

python {baseDir}/scripts/search.py "quantum computing" --format markdown

Formatted markdown with headers, bold text, and links.

JSON format:

python {baseDir}/scripts/search.py "quantum computing" --format json

Structured JSON data for programmatic processing.

10. Saving Results to File

Save search results to a file:

python {baseDir}/scripts/search.py "<query>" --output <file-path>

Example:

python {baseDir}/scripts/search.py "artificial intelligence" --output ai_results.txt
python {baseDir}/scripts/search.py "AI news" --type news --format markdown --output ai_news.md
python {baseDir}/scripts/search.py "AI research" --format json --output ai_data.json

The file format is determined by the --format flag, not the file extension.

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

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": Sync or reinstall the OpenSquilla project dependencies
• 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 {baseDir}/scripts/search.py "topic" --max-results 15 --output topic_web.txt

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

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

Programmatic Processing

Use JSON output for automated processing:

python {baseDir}/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 {baseDir}/scripts/search.py "topic1" --format markdown --output kb/topic1.md
python {baseDir}/scripts/search.py "topic2" --format markdown --output kb/topic2.md
python {baseDir}/scripts/search.py "topic3" --format markdown --output kb/topic3.md
