Find-Package does not find packages without wildcard character

[andref15]

Steps to reproduce

When searching for a NuGet Package with the Find-Package command no packages are found unless you add a wildcard character to the value of the name parameter.
Find-Package -Name PackageName -Source Test -Credential (Get-Credential) does not work but
Find-Package -Name PackageName* -Source Test -Credential (Get-Credential) does

The problem with this behavior is that it's not possible to find a package by the exact name, so a package called PackageName123 would also be returned and it also is not possible to combine a wildcard search with the AllVersions flag

Expected behavior

PS> Find-Package -Name PackageName -Source Test -Credential (Get-Credential)
Name                           Version          Source           Summary
----                           -------          ------           -------
PackageName                    1.0.0            Test             Package Description

Actual behavior

PS> Find-Package -Name PackageName -Source Test -Credential (Get-Credential)
Find-Package: No match was found for the specified search criteria and package name 'STYX.Blazor.UI.Attribute'. Try Get-PackageSource to see all available registered package sources.

PS> Find-Package -Name PackageName* -Source Test -Credential (Get-Credential)
Name                           Version          Source           Summary
----                           -------          ------           -------
PackageName                    1.0.0            Test             Package Description
