Chapter 1, Getting Started with ElasticSearch Cluster, covers ElasticSearch installation and configuration, REST API usage, mapping configuration, routing, and index aliasing.

Chapter 2, Searching Your Data, discusses Query DSL—basic and compound queries, filtering, result sorting, and using scripts.

Chapter 3, Extending Your Structure and Search, explains how to index data that is not flat, how to handle highlighting and autocomplete, and how to extend your index with things such as time to live, source, and so on.

Chapter 4, Make Your Search Better, covers how to influence your scoring, how to use synonyms, and how to handle multilingual data. In addition to that, it describes how to use position-aware queries and check why your document was matched.

Chapter 5, Combining Indexing, Analysis, and Search, shows you how to index tree-like structures, use nested objects, handle parent-child relationships, modify your live index structure, fetch data from external systems, and speed up your indexing by using batch processing.

Chapter 6, Beyond Searching, is dedicated to faceting, "more like this", and the prospective search functionality.

Chapter 7, Administrating Your Cluster, is concentrated on the cluster administration API and cluster monitoring. In this chapter you'll also find information about external plugin installation.

Chapter 8, Dealing with Problems, will guide you through fetching large results sets efficiently, controlling cluster rebalancing, validating your queries, and using warm-up queries.
