How do I search the Wayback Machine for URLs on a website that contain a specific string?

I am looking for a way to search on archive.org for URLs of a website, that contain a certain word.

(all my explanations here use 'example.com', but it's not the actual website I am searching for)

When I search for the website in the 'URLs', I find over 10000 entries for the site.I then use the integrated filter to look for the word 'Baum'. That results in about 90 entries.But if I search for the URL 'example.com/baum', I find over 800 entries, with 0 overlap to the previous 90 hits.The 2nd way misses entries like 'example.com/2baum'.A search for 'example.com*baum' results in an empty result.

The help website mentions fuzzy URL matching, without going into details about it.
