What is it?

TNTSearch is a PHP library for adding full-text search to an application without running a separate search server. You point it at a data source such as a SQLite, MySQL, or PostgreSQL database or a folder of text files, build an index file, and then run queries against it. Indexes are stored in SQLite by default, with MySQL and Redis engines also available, and they can be updated with insert, update, and delete calls without a full rebuild.

Search supports relevance ranking with BM25 and TF-IDF, boolean queries with AND, OR, and NOT, fuzzy matching with configurable edit distance, and search-as-you-type prefix matching. It also includes stemmers for several languages, custom tokenizers, result highlighting and snippets, geo-based nearest-point search, and a simple text classifier.

The search methods return document IDs and scores rather than full rows, so the application fetches the matching records from its own database and keeps the returned order. A Laravel Scout driver is available as a separate package.
