Hibernate Search by Example

Overview of this book

<p>Users expect software to be highly intelligent when searching data. Searches should span across multiple data points at once, and be able to spot patterns and groupings in the results found. Searches should be able to fix user typos, and use terms related to the user’s search words. Searching is at its best when it pleasantly surprises us, seeming to understand the real gist of what we’re looking for better than we understood it ourselves! Where can we find such a search system and how can we use it efficiently? <br /><br />Hibernate Search by Example is a practical, step-by-step tutorial, which guides you from the basics of Hibernate Search to its advanced features. The book builds toward a complete sample application, slowly fleshed out to demonstrate each and every concept being introduced in each chapter. By the end you will have a solid foundation for using Hibernate Search in real production applications.<br /><br />This book starts with a simple example, and incrementally builds upon it to showcase each Hibernate Search feature introduced. By the end of the book you will have a working, functionality-rich application, and a deeper understanding than you might have had from looking at code snippets in a vacuum.</p> <p>You will learn how to integrate search into core Hibernate applications, whether they are XML or annotation-based, or if you are using JPA. You will see how to fine-tune the relevance of search results, and design searches that can account for user typos or automatically reach for related terms. We will take advantage of performance optimization strategies, from running Hibernate Search in a cluster to reducing the need for database access at all.</p> <p>Hibernate Search by Example provides everything you need to know to incorporate search functionality into your own custom applications.</p>

Summary


In this chapter, we learned how to work with applications in a modern distributed server architecture, to allow for scalability and better performance. We have seen a working cluster implemented with a filesystem-based directory provider and JMS-based backend, and now have enough knowledge to explore other approaches involving Inifinispan and JGroups. We used sharding to split a Lucene index into smaller chunks, and know how to go about implementing our own custom sharding strategy, if necessary.

This brings us to the end of our little adventure with Hibernate Search! We have covered a lot of critical concepts about Hibernate, Lucene and Solr, and searches in general. We have learned how to map our data to search indexes, query and update those indexes at runtime, and arrange it all in the best architecture for a given project. We did all of this through an example application, that grew with our knowledge from simple to advanced along the way.

There's always more to learn. Hibernate...
