Working On ElasticSearch Using .NET NEST step by step

Either take it from this link https://www.nuget.org/packages/NEST/ OR Use Install-Package NEST -Version 6.5.0

Now you are ready to work on Elasticsearch through .NET.

Now follow the below steps to proceed further:

Step 6

Add Namespace in your Controller. This will give you facility to connect with your Elasticsearch instance from your .Net code.

Here points to note is that "index" is Database and "type" is Table. so you need to create INDEX(Database) first, then you need to create TYPE(Table) so that you can insert data in table in the format of JSON.

Step 7

Please add the below code to connect and create index, type and insert data in it. I have created a complete API as a sample for your reference. Below code is in working state.
