[Observium] What boolean operators are available when creating groups ?

Hi!

I've been using equals and match and wildcard (*) when aggregating together data in the group feature, however I now have to create a group where I need to exclude certain things and select others with wildcard.

I am not sure this works, and I can't find anything in the documentation about it.

basically I need to include all hosts with a certain hostname pattern, except a few ones with a slightly different pattern. If I wrote it in two lines, it would be like this :

hostname match foo-is*.bar.com hostname != foo-is4*.bar.com

Anyway way to do this ?
