The app is normally used to check for profiles that might not be sourced or have style issues, but when you enter something in the Search box, it will also return the profiles where that text is found. Ref_0 is a common term in gedcom profiles that have not been 'cleaned'.
The Search? Column will have 'Found' for the records where that Search text was found. You can sort by the headings, if you want to work on a surname, as an example.
You can 'Download CSV', if desired, to have a list to work from
