Lucene is a high-performance, scalable, search engine technology. Both indexing and searching features make up the Lucene API.

The first argument is a File object indexDir that corresponds to the directory where the index will be created. The second argument is another File object dataDir that corresponds to the directory to be indexed.Read full article from Journal of Learning Apache Lucene - Lucene In Action | I love programming
