The Chrome OS team is experimenting with Files App search results in the Chrome Launcher in the latest Dev Channel update.

Give it a try! Enable the flag "Launcher Search Provider API" at chrome://flags/#enable-launcher-search-provider-api, restart your session and search for anything you've downloaded or stored in Google Drive.
If the search result is a directory, it will open it in the Files app, otherwise it will try to execute the default task.
