You can perform ad hoc targeting or blocking of users based by an advanced query on general attributes, organization hierarchies, geolocation, user attributes, or device types.

1. In the Affected Users section, click the By Advanced Query tab.
2. Select the AND/OR operator. When AND is selected, users must meet all conditions to be targeted in the event. When OR is selected, users that match any of the conditions are targeted. The default is AND.
3. Click Add Condition.
4. In the Select Attribute list, select the first attribute, organization hierarchy, geolocation, user attribute, or device you want to use as targeting criteria.
5. In the Select Operation list, select the operation that you want to assign to the attribute. To block users who have specific attributes, select a negative operation such as not equals or does not contain.
   Note: The list of operations varies depending on the type of attribute selected.
6. If the operation you selected in Step 5 requires additional query values, a third field appears on the screen. Enter or select a value for the attribute.
7. Optionally, click Add Condition and then repeat steps 3 through 6 for each additional condition you want to add. The Affected Users Summary field at the bottom of the Affected Users section updates automatically to display the total number of users who match the query conditions you have created.
8. Optionally, modify the query conditions as needed to isolate the exact user group you want to send event-generated alerts to. You can click Add Condition to add more conditions or click to remove an existing condition.
9. Optionally, in the Affected Users Summary section, click the number in the By Advanced Query field to view a screen that displays the criteria that you created for the advanced query.
