This feature is only available in Professional and Enterprise Editions.
Identity Finder provides the ability for you to enter your own User Defined Identity Match Type to search for anything else that is not captured by another Identity Match Type. For example a specific personal healthcare record, an account id, or a keyword like "crime". It uses Unique Searching Using Your Personal Information to find your User Defined Types in the specific format you provide.
Identity Finder will not search for User Defined Identity Matches until you provide specific personal information. The information you enter is case sensitive.
If you are using the Startup Wizard, you can choose to add specific, unique User Defined Identity Matches to the search.
If you are not using the Startup Wizard, you can also Add a User Defined Identity Match to the Unique Identity Include List via the "Include List" page of the "Identity Finder Personal Information File" dialog box (you can open this dialog box by pushing the Add/Remove Information button on the What to Search for ribbon). With the Enterprise Edition you may use Regular Expressions to define your search criteria. Check the Enable RegEx Search for all User Defined Types to enable this feature.
Note: When entering a unique User Defined Identity Match, it must be entered as no more than 100 characters.
