Overview of this book

The Elastic Stack is a powerful combination of tools for distributed search, analytics, logging, and visualization of data from medium to massive data sets. The newly released Elastic Stack 6.0 brings new features and capabilities that empower users to find unique, actionable insights through these techniques. This book will give you a fundamental understanding of what the stack is all about, and how to use it efficiently to build powerful real-time data processing applications. After a quick overview of the newly introduced features in Elastic Stack 6.0, you’ll learn how to set up the stack by installing the tools, and see their basic configurations. Then it shows you how to use Elasticsearch for distributed searching and analytics, along with Logstash for logging, and Kibana for data visualization.

Summary


In this chapter, we took a deep dive into the search capabilities of Elasticsearch. We understood the role of analyzers and the anatomy of an analyzer. We have seen how to use some of the built-in analyzers that come with Elasticsearch, and we have also seen how to create custom analyzers. Along with a solid background regarding analyzers, we learnt about two main types of queries—term-level queries and full-text queries. We also understood how to compose different queries into more complex queries using one of the compound queries.

This chapter provided you with sound knowledge to get a foothold for querying Elasticsearch data. There are many more types of queries supported by Elasticsearch, but we have covered most essential ones. This should help you get started and help you understand other types of queries from the Elasticsearch reference documentation.

In Chapter 4Analytics with Elasticsearch, we will learn about the analytics capabilities of Elasticsearch. With that chapter...
