Filter questions/help

I have 1 feed that I want to filter on. I am not sure if this is even possible.
So, I only want to see articles with the words foo and bar and then anything else can just be marked as read.

Is that possible to do it in 1 filter? Right now I could only figure out how to make foo be filtered to a label, and then bar filtered to the same label. It required 2 filters to do it.

thanks

Filters support regular expressions so you should be able to just do something like foo|bar and it should match; you want everything without so you’ll check/select the inverse regular expression matching.

nice!! thank you very much.
