Regex expression naming

Question

Version 8.4 (2823) Feature release (14 May 2018) has introduced new feature: Regex expression naming, e.g. REGEX:ssn “\d{3}-?\d{2}-?\d{4}”

How can I use it? Can you give examples where it adds value? In what part of the search string can I refer to the regex name?

Attempting to search at https://help.mythicsoft.com/filelocatorpro/en/index.html fails, no hits about 'regex expression naming'. Maybe good idea to update the documentation as well...

Thanks!

The naming feature is intended for reporting. The default name for on the Keyword Report is the actual expression itself, which for a large expression would be difficult to read. For example:

Keyword Name                               Count  
                                              
\d{3}-?\d{2}-?\d{4}                        6,416  
\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}\b  714    

Looks much better as:

Keyword Name  Count  
                 
SSN           6,416  
Email         714
