Learn how to use Elasticsearch, an open source, distributed, RESTful search engine built on top of Apache Lucene. Each chapter in this book tackles a particular facet of Elasticsearch with separate sections for beginners more advanced programmers. If you're a beginner, advanced techniques are not required reading, but you can revisit them once you have a solid understanding of the basics.

This book explains concepts such as full text search, near real time visibility of search data, lack of transactions, and NoSQL-style denormalization from first principles, enabling beginners to glean sufficient information to get up and running with Elasticsearch.

Whether you need full-text search or real-time analytics of structured data—or both—the Elasticsearch distributed search engine is an ideal way to put your data to work. This practical guide not only shows you how to search, analyze, and explore data with Elasticsearch, but also helps you deal with the complexities of human language, geolocation, and relationships.

If you’re a newcomer to both search and distributed systems, you’ll quickly learn how to integrate Elasticsearch into your application. More experienced users will pick up lots of advanced techniques. Throughout the book, you’ll follow a problem-based approach to learn why, when, and how to use Elasticsearch features.
