Currently, FindDuplicate tries to find a duplicate by doing a search, that cannot be tuned by the library. It would be better to have the opportunity to use the matching points system. A "FindDuplicate" matching point entry could be added, set to title/author -current behaviour of FindDuplicate-, that the library can update/change to fit it's needs.
I like this idea! I was just about to open a ticket because I wanted to add a few indexes (like identifier-standard for 024$a and 022$a and Control-number for 001)to FindDuplicate (which have already been implemented locally). Using record matching rules might really be the best way to do this, since different libraries might have different needs/wants for how to find duplicates.
We'd love to add 001 to the checks as this is the most important field for our synchronization with the union catalog.
