Lots of people read these forums, and many of them will simply skip over a post that is difficult to read, because it's just too large an investment of their time to try and follow a wall of badly formatted text.

The main question I have is why are you indexing an array of items if you actually want to compute items. Just indexing individual items is looking a better design to me but may be I don't have the full picture here.
So I'd index things like:
PUT items/_doc/1234
{
"itemname": "1234",
"quantityint": 2
}
PUT items/_doc/1234
{
"itemname": "1235",
"quantityint": 2
}
So basically its a list of object in java that i'm trying to create equivalent mapping of . In a single request there can be multiple items , therefore i've mapped the object as nested .
Is there a way to fetch only the corresponding quantity of a given item in an array of items for a given object?
I was not speaking about the implementation details but about the need.
If you are trying to compute on "item", then index "item" and not a group of items.

I don't know but may be provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.
A full reproduction script will help readers to understand, reproduce and if needed fix your problem.
