using get-CimInstance to "list" a keyword

PS MOL 14.6 (Using Get-CimInstance) there’s a caveat about no -list parameter.

So how do I query CIM for a keyword similar to:

Get-WmiObject -list *product

Only thing I can find is:
Get-CimClass -Namespace root\cimv2

but I don’t want to go through that whole list.

Is WMI explorer my only option?

Get-WmiObject -List *product
Get-CimClass -ClassName *product

Give the same output.

thank you Matt
