When you are connected to a vCenter Server system with the vSphere Client, you can search the vSphere inventory for virtual machines, hosts, datastores, networks, or folders that match specified criteria.
If the vSphere Client is connected to a vCenter Server system that is part of a connected group in vCenter Linked Mode, you can search the inventories of all vCenter Server systems in that group. You can view and search only for inventory objects that you have permission to view. Because the search service queries Active Directory for information about user permissions, you must be logged in to a domain account to search all vCenter Server systems in Linked Mode. If you log in using a local account, searches return results only for the local vCenter Server system, even if it is joined to other servers in Linked Mode.
If your permissions change while you are logged in, the search service might not immediately recognize these changes. To ensure that your search is performed with up-to-date permissions, log out of all your open sessions and log in again before performing the search.
