Let’s name it Before we go to create an index, we have to connect ElasticSearch server.Lot’s of things happening here.

It is the place to store related documents. In this Elasticsearch tutorial blog, I will introduce all the features which make the Elasticsearch fastest and most popular among its competitors. The very first thing we have to do is creating an index.
