Elasticsearch is the core of the widely-used ELK Stack (Elasticsearch, Logstash, and Kibana), a popular platform for log analytics and data search. Its central role has made "Elasticsearch" nearly synonymous with the stack itself. Known for its capabilities in search and log analysis, Elasticsearch is among the most popular database systems today.

Elasticsearch enables near real-time search over large datasets, supports vector searches, and integrates with generative AI applications, providing a versatile tool for modern data management. This tutorial introduces new users to Elasticsearch, covering essential topics like installation, initial indexing, and data handling. With Elasticsearch, users can explore powerful search features, gain insights from complex data, and enhance applications with advanced analytics in real-time.
