I gave it a try and figured it out. You only have to write "True" and not "True" (space) "Rivas". There is a bug in my opinion in the search box that prevents you from finding people whose names have spaces in them. I understand that according to whoever designed this search function I should only write the first part of the name and then stop and start scrolling through the list of results which by the way doesn't even appear sorted alphabetically. In the end I found the person by scrolling through this list (it is the twelfth result).
