This is meant to demonstrate the ability to implement full-text searching capabilities using Hibernate Search with a relational database (using in-memory H2 for simplicity's sake here.)
Using Spring Data JPA, two entities are defined: BookEntity, AuthorEntity.
There is a many-to-many relation between Books and Authors. I.e.: A book can be associated to many authors, an author can be associated to many books.
The entry point is the BookDao. There are a few sample full text queries, including searching
for books by title, and a faceted search example using author as the facet.
See BookDaoIntegrationSpec for specific calls.
