If the collection lexicon is on, I would expect it to be correct.

Subject: [MarkLogic Dev General] Collection counts using xdmp:estimate

Will this query give me a vaild count result?
for $collection in cts:collections()
return
element result {
   element collection {$collection},
   element count {xdmp:estimate(collection($collection))}
}

Also, if I backup a database on an ML 4.2-7 cluster and restore it on ML7, 
should running the same query give the same results.
for $collection in cts:collections()
return
element result {
   element collection {$collection},
   element count {xdmp:estimate(collection($collection))}
}
