On top of John's answer, I would like to point out that Hibernate Search integrates full-text queries into the Hibernate world very nicely, so it's really like a new way to query your domain model in Hibernate applications.
Chapter 1 describes nicely what you gain with full-text search and what problems it poses. It used to be available for free on manning's website, not sure it is still the case though.
