To find someone, you have to enter last name, first name. However, if that person isn't on the first screen, their name won't appear first, and you'll have to search through the entire list.
For example: Zimmer, Uriel. Open "Contractors" and type this name in the "Search" field. It won't appear, even though it's included.
