Jack, I see the source of your confusion...
the "Search G2G" button will search the discussion forum here for the string of letters you've typed into the box (including the dash and numbers, which it likely won't find being discussed).
The search box on your profile page is trying to find a genealogy list of surnames (which will never include a dash and numbers). The "tennis racket" is really a "magnifying glass", intended to signify searching :)
As Dave and Cynthia were suggesting though, is to go higher, into your web browser URL search bar (which some browsers hide by default these days), and have to modify the string of letters and slashes in that area, replacing your profile ID number with the one you're hoping to find.
Cynthia gave you the link to that one already. Just click on her link.
You can see it differs from yours because it has the word "wiki" between the slashes, while yours has the word "genealogy" there instead.
Hope this helps clear up some confusion.
