You can't do anything like that with fn:collection. But if you
have the collections lexicon enabled for the database, you can use
cts:collections to get a list of all collection names and filter it
for the ones that match your pattern. You can then use those collection
names to count how many documents are in each:
for $collection-name in cts:collections()
where fn:contains ($collection-name, "/Dept/Eng/")
return xdmp:estimate (fn:collection ($collection-name))
