Hibernate Search builds on the Lucene feature set and offers an easyto- implement interface that integrates seamlessly with Hibernate-the leading data persistence solution for Java applications. Hibernate Search Enterprise and web applications require full-featured, "Google-quality" search capabilities, but such features are notoriously difficult to implement and maintain. Hibernate Search in Action introduces both the principles of enterprise search and the implementation details a Java developer will need to use Hibernate Search effectively. This book blends the insights of the Hibernate Search lead developer with the practical techniques required to index and manipulate data, assemble and execute search queries, and create smart filters for better search results. Along the way, the reader masters performance-boosting concepts like using Hibernate Search in a clustered environment and integrating with the features already in your applications. This book assumes you're a competent Java developer with some experience using Hibernate and Lucene. Also available is all code from the book.

At first, it may not be obvious why you'd need such a thing -- after all, your data is nicely filed away in a decent relational database.

While an RDBMS can do a great job of providing transactional CRUD operations on data stored in a relational model, search functions defined in SQL are not always capable of meeting both the functional and non-functional requirements of your projects. There are a number of query types that RDBMSs in general do not support without vendor extensions: Fuzzy queries, in which "fuzzy" and "wuzzy" are considered matches Word stemming queries, which consider "take," "took," and "taken" to be identical Sound-like queries, which consider "cat" and "kat" to be identical Synonym queries, which consider "jump," "hop," and "leap" to be identical Queries on binary BLOB data types, such as PDF documents, Microsoft Word or Excel documents, or HTML and XML documents More disappointingly, SQL search results are not ranked by match-relevance scores.

The SQL standard is simply not intended for full-text querying. Lucene search capabilities, on the other hand, are unlimited. Lucene handles all the queries just mentioned, and more; it also allows you to find text documents similar to other documents through its advanced term-vector query.

For instance, you could search the content of a number of books to find one with content similar to that of Hibernate in Action. The analyzer architecture in Lucene leverages Java's built-in internationalization and localization capabilities, which makes full-text query available for various languages worldwide. Lucene delivers outstanding performance through some innovative techniques, such as an inverted index.
