Hi Morris,

thanks for your feedback.

I tried out the QueryCollection example from github and discovered there is a bug in line 47

for $doc in collection()

The original example shouldn’t cause any problems, because the non-argument function call will reference the database that has been created in line 28 (and the code seems in fact to work on my system). Did you modify the code a little? What BaseX version have you been using for testing?
