@DGrey, one more thing: as noted above by @vsr1, my code in the Documents view is not efficient when you have a very large data set, and a WHERE clause that is not very selective (meaning that it matches many documents). Do you need to use the WHERE clause? If so, can you make it more selective, so it returns a smaller set of documents?
Another possibility would be to run the same query, in the query workbench, without the “ORDER BY” clause, which is causing the performance issue.
