MG4J (Managing Gigabytes for Java) is a free full-text search engine for large document collections written in Java. As a by-product, it offers several general-purpose optimised classes, including fast & compact mutable strings, bit-level I/O, (possibly signed) minimal perfect hashing for very large strings collections, etc.
With release 1.1, MG4J becomes a highly customisable, high-performance, full-fledged search engine providing state-of-the-art features (such as BM25 scoring) and new research algorithms. Release 2.0 significantly improved performance and introduced several new features.
