Clicking the Search menu item will present you with a dialog to find computers by their hostname. OVERLAPS will remember the last 10 searches you performed within 30 days and allow you to select from them to perform the search again.
If the Search window is opened while viewing a computer container, you will have an additional checkbox to limit the results to that container and any child containers beneath it.
Search results are grouped by Active Directory container, and function just like a normal computer list.
Clicking your search term at the top of the results allows you to refine your search or to include the computer’s description in the search.
