What do you mean by _compare_? Compare the values that are indexed for each field for each document?

Lets assume you've Index called people & there we've following fields  
1.Name (which have full name)  
2.First Name  
2.Last Name  
3.Middle Name  
4.Email  
5.Address

Now I want to compare 1.)Name & 2.) Full Name through out the index, so how can I do in Nest(c#) ?

Hope this will help you.

That helps a little; how are you looking to compare them? What _kind_ of comparison are you looking to perform?
