# DuckDuckGo Search via web_fetch
|
||
|
||
Search the web using DuckDuckGo Lite's HTML interface, parsed via `web_fetch`. No API key or package install required.
|
||
|
||
## How to Search
|
||
|
||
```
|
||
web_fetch(url="https://lite.duckduckgo.com/lite/?q=QUERY", extractMode="text", maxChars=8000)
|
||
```
|
||
|
||
- URL-encode the query — use `+` for spaces
|
||
- Use `extractMode="text"` (not markdown) for clean results
|
||
- Increase `maxChars` for more results
|
||
|
||
## Region Filtering
|
||
|
||
Append `&kl=REGION` for regional results:
|
||
|
||
- `au-en` — Australia
|
||
- `us-en` — United States
|
||
- `uk-en` — United Kingdom
|
||
- `de-de` — Germany
|
||
- `fr-fr` — France
|
||
|
||
Full list: https://duckduckgo.com/params
|
||
|
||
### Example — Australian search
|
||
|
||
```
|
||
web_fetch(url="https://lite.duckduckgo.com/lite/?q=best+coffee+melbourne&kl=au-en", extractMode="text", maxChars=8000)
|
||
```
|
||
|
||
## Reading Results
|
||
|
||
Results appear as numbered items with title, snippet, and URL. Skip entries marked "Sponsored link" (ads) — organic results follow.
|
||
|
||
## Search-then-Fetch Pattern
|
||
|
||
1. **Search** — query DDG Lite for a list of results
|
||
2. **Pick** — identify the most relevant URLs
|
||
3. **Fetch** — use `web_fetch` on those URLs to read full content
|
||
|
||
## Tips
|
||
|
||
- First 1-2 results may be ads — skip to organic results
|
||
- For exact phrases, wrap in quotes: `q=%22exact+phrase%22`
|
||
- Add specific terms to narrow results (site name, year, location)
|
||
|
||
## Limitations
|
||
|
||
- No time/date filtering (DDG Lite doesn't support `&df=` reliably via fetch)
|
||
- Text results only — no images or videos
|
||
- Results sourced from Bing (may differ from Google)
|
||
- Google search does NOT work via web_fetch (captcha blocked)
