VERDICT
A bit like Solr, but much smaller and not as bright - lunrjs.com
Worth it. Buy it if you run a blog, docs site, or small-to-medium static site and want free search with no backend. Skip it for large datasets, frequently changing content, or if you need hosted search and real support.
Medium. Based on ~25 public sources; no formal review-platform ratings found, so user sentiment comes from tutorials and dev threads.
