Did you try this with item-frequency passed in as an option to cts:sum-aggregate?

Subject: [MarkLogic Dev General] cts:sum-aggregate returned incorrect result
I'm testing the cts:sum-aggregate function on a database with 100 million documents. There exists a range index for an element, num, I used for this test.
This returns the result
==> 832,332,413 (: commas inserted for viewing :)
Since I know that num falls in the range of 1980 - 2010 and I know every document in the collection has exactly one 'num' element. I expect the result to be around
I also verified by running the DEPRECATED function, cts:sum
cts:sum(cts:element-values(xs:QName("num"), (), ("type=int")))
The result from cts:sum is what I had expected:
==> 202,695,795,325 (: commas inserted for viewing :)
I also did another test in a smaller database, here, the cts:sum-aggregate function gave the correct result. Can someone explain?
