Introduction

Hibernate Search is a library that combines the strengths of full text search using ​Lucene with ​Hibernate's O/R mapping capabilities. Queries in Hibernate Search are expressed as Lucene queries.

Directory

A Lucene index is represented by a Directory. We will use a file system directory provider to persistently store the Lucene index; and we will use an in-memory directory provider to use with unit test.
