Understanding Elasticsearch REST API

Understanding Elasticsearch REST API

The Elasticsearch REST API is based on the principles of Representational State Transfer (REST) and allows us to perform CRUD (Create, Read, Update, Delete) operations on our Elasticsearch cluster using HTTP methods such as GET, POST, PUT, and DELETE. The REST API provides a simple and intuitive interface for interacting with Elasticsearch and making it accessible to developers of all skill levels....

Basic Concepts of Elasticsearch REST API

Before we perform the examples of interacting with Elasticsearch via its REST API, let’s cover some basic concepts:...

How it Works

To understand the Interacting with Elasticsearch in well manner. We will consider below sample documents to perform operations and queries for better understanding....

Conclusion

Overall, the Elasticsearch REST API provides a straightforward and effective means of interacting with Elasticsearch and allowing developers to manage data with ease. By understanding the fundamental concepts of indexes, documents, queries, and mappings, developers can take help from the full potential of Elasticsearch for their projects. With examples defining common operations like indexing, searching, updating, and deleting documents, this guide has provided a solid foundation for working with Elasticsearch’s REST API...
