I'm trying to use the SPSiteDataQuery to return the contents of several lists across a site collection. The problem I'm having, though, is that while there are only a few documents at the root level of these lists, the lists have folders containing large amounts of items, which causes the Query to exceed the List View Threshold.
I know that SPQuerys allow you to do something like
query.ViewAttributes = "Scope=\"Recursive\""
to recurse, and removing that will just show the results of the root folder only. Is there a way of filtering out ListItems that are in subfolders with any sort of CAML query?
