I'm a beginner but the more I deal with Elasticsearch the more I'd like to dig deeper.  
Just I struggle a little to find the "Index" of Elasticsearch which is supposed to evaluate and process the REST-Queries.  
I have been a Java-Programmer for a while now but so far worked more with JSP and JSF but have never used Gradle for my builds.  
Despite finding the /elasticsearch/server/src/main/java/org/elasticsearch/index/Index.java I presume this class has an entirely different background.

Maybe someone could provide a little more information? Which class provides the functionality when I'm sending a simple:  
`curl -X POST 'http://localhost:9200/my-index-000001/_doc?pretty' -H 'Content-Type: application/json' -d '`
