In a post I made a few years ago, I described how you can add WebCenter Content (UCM at the time) search to the browser's search engines. I think this is a handy shortcut if you find yourself performing searches often enough in WCC.
Well, in the PS5 release, this was actually included as a new feature. You need to enable the DesktopIntegrationSuite component in order to access it. Once you do, go to the My Content Server -> My Downloads link. There you will see the 'Add browser search' link.
