Apache Lucene (apache-lucene)

Today, I created an example to demostrate how BooleanQuery works and two different ways to construct a boolean query, using default constructor and using query builder.

Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java. It is a technology suitable for nearly any application that requires full-text search, especially cross-platform. It is an open source project available for free download.
