need a specialist solution for Server TM duplicates cleanup

I am working with a very large server TM that has a number of duplicates.

I am aware of opening the TM in the Translation Memories management interface and the search Type "search in potential duplicates only", which then takes me screen by screen to all "potential
 duplicates.

Is there a way to get "100% duplicates only" (not fuzzy, as there are many from formatting, etc.), so that they can be cleaned up.

I don't know if Regex can help write the filter.

I do not know how to compose the expression.

Can anyone help?

Thank you very much in advance.

Sincerely

Susanna Miles
