Lunr.js is a small, browser-based full-text search library developed in the olivernn/lunr.js project. It indexes JSON documents locally and provides a search interface that returns matching document references, relevance scores, and match metadata; it can generate the search index used by static sites such as microblogs. It supports field-specific searches, query-time term boosting, document-level index boosting, wildcard and edit-distance fuzzy matching, and full-text search in 14 languages. The library can be included directly in a web page or installed through npm, and is intended for client-side searching without a server-side search service or network connection.
