OR	cat OR dog	Either term

Time Filters (Google)

Privacy-Oriented Search

• DuckDuckGo: No tracking; HTML endpoint works well with web_fetch.
• Brave: Independent index.

Bangs Shortcuts (DuckDuckGo)

Use inside the q parameter on duckduckgo.com (many bangs redirect to third-party sites when used in a browser; web_fetch only retrieves the DuckDuckGo URL you request).

Bang	Role
!g	Run query on Google
!brave	Run query on Brave Search

WolframAlpha Queries

• Math: integrate x^2 dx
• Conversion: 100 USD to CNY
• Stocks: AAPL stock
• Weather: weather in Beijing
