ElasticSearch Quick Start
ElasticSearch Quick Start
An introduction to ElasticSearch in tutorial form.
About the Book
This book is intentionally short. While there are several books about ElasticSearch that will teach you just about everything this book doesn't try to do that. Instead it's goal is to get you as a developer or user of ElasticSearch started quickly. As such you won't find much theory or anything about configuring ElasticSearch for production use in this book. What you will find though is tutorials focusing on the basics as well as the (in my opinion) most common use cases.
After reading this book my goal is that you should know:
- How to install ElasticSearch and how to communicate with it
- How to index and remove documets
- How to search for documents and aggregate data from them
- How to create mappings, including dynamic mappings
