If you have checked a record for fuzzy duplicates, you can view the fuzzy duplicate check history for that record. The history shows all fuzzy duplicate checks that are done for the record.

You can clean up the logged fuzzy duplicate check history manually or in recurring mode.

For example, you want to keep fuzzy duplicate check history records for one month. Each week, you can do a cleanup, deleting history records older than one month.
