When to Use DuckDuckGo Search

Use DuckDuckGo search when the user asks about:

1. Current events and news - Recent happenings, breaking news, current affairs
2. Real-time data - Stock prices, weather, sports scores, exchange rates
3. Recent information - Events, releases, or changes after your knowledge cutoff
4. Specific facts - Population, statistics, dates that may have changed
5. Technical documentation - Latest API docs, library versions, tutorials
6. Local information - Business hours, addresses, phone numbers
7. Product information - Prices, availability, reviews

When NOT to Use DuckDuckGo Search

Avoid searching when:

1. General knowledge - Well-established facts that won't change
2. Simple calculations - Use the calculator tool instead
3. Creative tasks - Writing, brainstorming, analysis
4. Personal advice - Relationship, life decisions
5. Subjective opinions - Preferences, recommendations without factual basis

Choosing the Right Search Provider

Search Query Best Practices

Do:

• Use specific, focused queries
• Include relevant keywords
• Add context like dates, locations, or names
• Break complex questions into simpler searches

Don't:

• Use overly long queries (keep under 10 words when possible)
• Include unnecessary words like "please" or "can you tell me"
• Ask questions as full sentences (use keywords instead)

Examples of Good vs Bad Queries

Handling Results

1. Summarize the key findings from search results
2. Cite sources when providing specific information
3. Indicate uncertainty if results are conflicting or unclear
4. Suggest follow-up searches if the initial results are insufficient
5. Combine multiple searches for comprehensive answers

Limitations

• DuckDuckGo uses the ddgs library (free, no API key)
• Results depend on DuckDuckGo's index
• Some recent events may not be indexed immediately
• Paywalled content may show limited snippets
• Results are in English by default
