SearXNG backend additionally returns answers, infoboxes, suggestions, and unresponsive_engines when the instance provides them.

Backends

DuckDuckGo

Zero setup. The plugin POSTs to html.duckduckgo.com/html/ and parses the result page. Caveats:

• DuckDuckGo rate-limits aggressive use and may serve a CAPTCHA page (the plugin detects this and returns an error message).
• This is HTML scraping, not an official API. The tool may break if DuckDuckGo changes their layout.

For occasional use it's perfectly fine. For high volume, switch to SearXNG.

SearXNG

Requires an instance whose settings.yml has the json format enabled under search.formats. Most public instances disable it to discourage scraping, so you usually need to either:

• Self-host SearXNG (see searxng/searxng-docker) and add json to the formats list in settings.yml.
• Find a public instance that allows JSON. searx.space lists public instances; verify by hitting https://<instance>/search?q=test&format=json in your browser.

If you get the error SearXNG did not return JSON, the instance has the JSON format disabled — pick another one or self-host.

Install

One-click (macOS, Windows): Run in LM Studio

Linux (AppImage): the lmstudio:// deep link doesn't work out of the box because the AppImage doesn't register a scheme handler. Use the CLI instead:

To fix the deep link permanently, create ~/.local/share/applications/lmstudio.desktop:

Then:

After install: the plugin isn't enabled in chats by default. In any chat, click the tools button (bottom right of the chat input) and enable web-search.
