Hi,

Your expression looks a bit weird in the question because you didn't use the code button and some symbols weren't escaped.
In any case, you could try with something like:

index=abc123 
| eval app=case (
    application=="Application_1", "app_id_1",
    application=="Application_2", "app_id_2",
    1==1, "other"
)
| stats count by app

Which includes a matching for the two types of application names you want to match, but also a third option which is always true in case none of the previous matches work.

Hope that helps
J
