I have used elasticsearch library in node js and build a simple app which can fetch any key from elastic index .

Example:  
API POST End Point: [http://localhost:8000/serach/index\_name/doc\_type](http://localhost:8000/serach/index_name/doc_type)  
data:  
{  
"\_source": ["user","email"],  
"query": ...,  
"size": ...  
}

I want to know which class i will use in java to achieve same thing.
