Elasticsearch is a powerful, open-source search and analytics engine based on Apache Lucene. It quickly stores,
searches, and analyzes large amounts of data by creating indexes, rather than searching the text directly. With
a document-based structure and easy-to-use REST APIs, it processes and returns data in JSON format, offering
fast and scalable performance.
Install Elasticsearch locally by running it on your machine. The simplest method is to use the official
Elasticsearch Docker image. For more details, check the Elasticsearch Docker documentation.
This code initializes an ElasticsearchHandler to connect to an Elasticsearch server running on localhost with specified
username and password. This setup allows for searching and managing data stored in Elasticsearch efficiently.
