Sonia,

The problem was that FindDuplicates was hardcoded and the library had no way to
change that.  So the following scenario is just one example of where
FindDuplicates fails libraries:

1. Stage DVD Marc Records
2. Use a rule to match on 024 (the identifier on many DVDs)
3. Find duplicates
4. Go to Acq and add staged file to basket
5. Koha says there are duplicates but there aren't instead it's matching on
Title & Author and matching DVDs to books because the DVDs don't have ISBNs

By using this patch we allow for libraries to choose how to find duplicates
instead of forcing them to use a hard coded script that they have no control
over.
