In Detail

We all want to find the information we are looking for. This demand brings more and more tools that try to make the full-text search topic easier to understand and introduce to applications. ElasticSearch is one of those tools. It is a cluster- and cloud-aware, high-performance, open source search server. It is written in Java and runs as a standalone full-text search server. ElasticSearch uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP and JSON APIs that make it easy to use from virtually any programming language. ElasticSearch is a fast, very scalable, and easy-to-use search engine that is enjoyable to use and work with.

This book begins by introducing the most commonly used ElasticSearch server functionalities - from creating your own index structure, through querying, faceting, and aggregations, and ending with cluster monitoring and problem diagnosis.

As you progress through the book, you will cover topics like starting ElasticSearch, creating a new index, and designing its proper structure. After that, you’ll read about the query API that ElasticSearch exposes, as well as about filtering capabilities, aggregations, and faceting. Last but not least, you will get to know how to find similar documents by using similar functionality and how to implement application alerts by using prospective search functionality called percolator. Some advanced topics like shard allocation control, gateway configuration, and how to use the discovery module will also be discussed. This book will also show you the possibilities of cluster state and health monitoring as well as how to use third-party tools.

If you are looking for a book that will enable you to use ElasticSearch more efficiently, or you are looking for a book to get started with the ElasticSearch server, then this is a book you should consider reading.
