Apache Lucene™ is an open source indexing and search library written in Java. It is ideal for any application that requires full-text search and is the de facto industry standard search library.
Azul Zing® maximizes performance and throughput of Apache Lucene and enables the use of large in-memory indices not possible with other JVMs.
"Azul’s innovative Zing JVM and pauseless GC now enable Apache Lucene project developers to explore use cases requiring large heaps, such as holding an entire search index in memory for faster searching."
