To improve the accuracy of duplicate searches, it’s important to refine your search criteria as much as possible.
For instance, if you search using only the address field, you may encounter many matches that aren’t true duplicates. This is because an "address" search considers any address data, meaning that even partial or similar address entries could be flagged as duplicates, even if they belong to different contacts. To minimize this, try to include additional data markers, such as name or phone number, for a more precise search.
