Preface

The world that we live in is hungry for speed, efficiency, and accuracy. We want quick results and faster without compromising the accuracy. This is exactly why I have written this book. I have penned down my years of experience in this book to give you an insight into how to use Elasticsearch more efficiently in today's big data world. This book is targeted at experienced developers who have used Elasticsearch before and want to extend their knowledge about how to effectively perform Elasticsearch indexing. While reading this book, you'll explore different topics, all of which connect to efficient indexing and relevant search results in Elasticsearch. We will focus on understanding the document storage strategy and analysis process in Elasticsearch. This book will help you understand what is going on behind the scenes when you send a document for indexing or make a query. In addition, this book will ensure correct understanding of the meaning of schemaless by asking the question—is the claim that Elasticsearch stands for the schema-free model always true? After this, you will learn the analysis process and about analyzers. More importantly, this book will elaborate the relationship between data analysis and relevant search results. By the end of this book, I believe you will be in a position to master and unleash this beast of a technology.
