Multi Search Engine v2.0.1

Integration of four search endpoints for web fetching without API keys.

Search Engines

| Engine | URL template | |--------|----------------| | Google | https://www.google.com/search?q={keyword} | | DuckDuckGo | https://duckduckgo.com/html/?q={keyword} | | Brave | https://search.brave.com/search?q={keyword} | | WolframAlpha | https://www.wolframalpha.com/input?i={keyword} |

Quick Examples

// Google
web_fetch({"url": "https://www.google.com/search?q=python+tutorial"})
web_fetch({"url": "https://www.google.com/search?q=site:github.com+react"})
web_fetch({"url": "https://www.google.com/search?q=machine+learning+filetype:pdf"})
web_fetch({"url": "https://www.google.com/search?q=ai+news&tbs=qdr:w"})
// DuckDuckGo
web_fetch({"url": "https://duckduckgo.com/html/?q=privacy+tools"})
web_fetch({"url": "https://duckduckgo.com/html/?q=!g+machine+learning"})
// Brave
web_fetch({"url": "https://search.brave.com/search?q=privacy+tools"})
// WolframAlpha
web_fetch({"url": "https://www.wolframalpha.com/input?i=100+USD+to+CNY"})

Advanced Operators (Google)

| Operator | Example | Description | |----------|---------|-------------| | site: | site:github.com python | Search within site | | filetype: | filetype:pdf report | Specific file type | | "" | "machine learning" | Exact match | | - | python -snake | Exclude term | | OR | cat OR dog | Either term |

Time Filters (Google)

| Parameter | Description | |-----------|-------------| | tbs=qdr:h | Past hour | | tbs=qdr:d | Past day | | tbs=qdr:w | Past week | | tbs=qdr:m | Past month | | tbs=qdr:y | Past year |

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
