With current implementation, running Find-PSResource without any parameters or other input from the user is allowable behavior. It queries for all non-prerelease, module type resources from the repository registered with highest priority ranking.

Creating this issue for further discussion on whether this is expected behavior or we should report an error message asking for more input with the cmdlet. One of the downsides of having this as allowable behavior is that this could put a large load performance wise on the gallery being queried. Additionally, such a large query could be made even if it wasn't the user's intention to run this command (i.e they may have hit enter before typing up the rest of the command). Steve had a suggestion to require '*' to signify it was a deliberate action. Currently, Find-PSResource '*' returns a single resource.
