i have an index of 14 million docs. (2.5 TB). I suspect there are around 2 million duplicates in that. I want to get the exact count of documents which have more than one copy. I want to do this based on a field which we know is unique to all those documents.  
( i know the query to get all duplicates. I need a query to get only the count )  
like count if min\_doc= 2  
count if FieldValue\>=2
