"IS NOT" condition doesn't filter out results when used with "OR" operator


Description

When using the condition builder (e.g. creating a Notification) to filter out specific results, the "IS NOT" condition doesn't work as expected when used along with an "OR" operator.

Cause

This is not a ServiceNow issue, there's a flaw in the logic with double negatives and OR operator.

Resolution

Use AND instead of OR. With that, you will ensure that the result will contain all "callers" except XXX and YYY.
