SearXNG Search Plugin for LM Studio

This plugin enables LM Studio assistants to search the web using a local SearXNG instance, providing privacy-focused metasearch capabilities similar to how Vane (Perplexica) utilizes SearXNG.

Prerequisites

• Running SearXNG Instance: You must have SearXNG installed and running locally (e.g. at http://localhost:8081 to prevent possible conflicts with other services)

• JSON API Enabled: Ensure your SearXNG settings.yml includes:

Installation

• Download this plugin from LM Studio Hub or install manually
• Configure the plugin settings in LM Studio:
  • SearXNG URL: Your instance URL (default: http://localhost:8081) (if a different port is used, update "config.ts" accordingly. Note that current port setting is "8081" to prevent possible conflicts with other services)
  • Default Results Count: How many results to return per query (1-20)
  • Timeout: Request timeout in milliseconds

Usage

Once installed, the plugin provides two tools:

• search_web: Search the internet using SearXNG
• fetch_page_content: Retrieve and extract text from specific URLs

The assistant will automatically invoke these tools when web search is needed.

Project Structure

Troubleshooting

• "JSON format not enabled": Ensure your SearXNG settings.yml includes json in search formats
• Connection timeouts: Verify SearXNG is running and accessible at the configured URL
• No results: Check that SearXNG has search engines enabled in its configuration

Comparison with Existing Solutions

Unlike the DuckDuckGo plugin which relies on DuckDuckGo's HTML scraping, this SearXNG implementation offers:

• Privacy control: Data never leaves your infrastructure (when using local SearXNG)
• Customizable sources: SearXNG aggregates 70+ search engines configurable by the user
• No rate limits: Local instances aren't subject to external API quotas
• Metadata richness: Access to result scores and source engine attribution
