Ben,
The upgrade to DSpace 6 did not modify legacy statistics records.
Statistics generated after your upgrade will contain UUIDs.
The following PR/ticket might provide some additional insight into the
issue. The statistics report tools look for UUIDs and legacy ids.
-
In dspace 6 solr statistics yesterday all owingItems were UUIDs. Today the
old ones(pre dspace 6) are back to the old IDs (pre dspace 6 ids)
So yesterday a query like
owningItem:d91e6a4e-4eb6-405e-bb42-407f82c1
would work
today for the same results I need to run
owningItem:4785
OR
