Java - elastic search

Hope you are all doing good .

Here I'm trying to make a java application and use elasticsearch in the application as a first stage i have made a simple Dynamic Web Java application with spring . In this application(Simple employee records application) i have a privileged login (Admin & User )

• Admin - He has all permission
• User - Read and edit permission alone

I'm trying to make use of elastic search in this application

Hope you would Help me to make use of the elasticsearch in the application so that i would be able to understand better about the elastic search.
