SearXNG in Rust
Engineers can reuse this library to add multi‑engine search capability without building their own crawlers or ranking logic. The server mode offers a ready‑to‑run HTTP endpoint with health checks and clear error responses, simplifying integration into existing services. The code also illustrates patterns for concurrent HTTP requests, HTML parsing with css selectors, and modular engine plug‑ins.

It sends a single query to four search engines simultaneously using reqwest and merges the results.
Results are deduplicated by stripping tracking parameters, locale prefixes and sorting query strings before applying a reciprocal rank fusion score.
The crate can be used as a dependency, run as a standalone server with environment‑controlled port and result limits, and extended by implementing the SearchEngine trait for new sources.
