What it says on the label.
I think it might be useful to at least combine several values for "Show records where…" filters, e.g. to exclude multiple country codes from a view without disabling logging for those countries entirely, e.g. "Show records where [Country Code] [is not equal to] [(US|GB|AU)]". The way it currently is, you can only define one such value at a time, so you can exclude either "US", or "GB" or "AU", but not all three of them. Or did I overlook something in the documentation?
