Filtering syntax?

[Rasmus256]

What is the syntax for the filtering? :)
Specifically I'm trying to filter to series that match any of two specific string literals, but can't quite seem to find the right way to do it..?

For anyone who might have this problem in the future: A workaround is to use filtering on tags instead of resource group or whatever. Tags can be anything, so pick an unused tag, select a good prefix (For instance "Cost"), group by the selected tag and use a filtering query: Cost*
