Elasticsearch in Action

A comprehensive guide to Elasticsearch — a popular search engine that allows real-time working with large volumes of data. The book contains practical advice on implementing modern search features in an application or website using Elasticsearch 8 and the open-source data visualization panel Kibana. It thoroughly describes the processes of data indexing, full-text query searches, working with term-level queries and compound queries, as well as data analysis and aggregation. The book also covers the architecture of Elasticsearch, data mapping mechanisms, working with documents, indexing operations, visualization with Kibana, creating clusters, and many other aspects. This is a comprehensive manual for those who want to deeply immerse themselves in the world of search engines and use Elasticsearch in their projects.
