Major Description
The background is I have implemented my own AccessManager. After executing a query and get back the RowIterator from the result, if I call rowiterator.getSize, it will return the size of all nodes matching my query (without honoring the access control) . But if I iterate through the result, I find lots of duplicates in the results; and if I filter out those duplicate, the final result is quite off the original number from RowIteartor.getSize()
BTW, I also disabled Doc Order sorting.
