somewhat related ... there are 2 hidden indexes in MarkLogic;
xdmp:document (uris enabled)
xdmp:collection (collection uris enabled)
which you might be able to leverage. The canonical example for these
indexes are as follows; which returns all uris along with their collection;
cts:element-value-co-occurrences(xs:QName("xdmp:collection"),xs:QName("xdmp:document),"map")
as this is hidden, I make no claims on support (as in there is none) ...
but thought it might be useful
