 Match filters check if a value matches a particular condition, which could be a regular expression or other match value.  List filters check to see if a value is found in a list. Click the Create output filter link to create an output filter. Select the output series you want to filter in order to view the remaining filter options. You can select any of the source fields that would be available to the output series, or any of the fields in the output series. This allows output filtering to be performed based on either the report data store, or the output series data. The types of output filter that are available are the same as used in the source filters. See "Source Filters" in this chapter for details about the types of filter that are available. The Match Rule allows you to construct more complex filtering rules. You can choose from the following matching rules:  Include item if filter matches - If the filter matches the item in the output series, the item will be included. The remaining filters will be applied in order.  Exclude item if filter matches - If the filter matches the item in the output series, the item will not be included. The remaining filters will be applied in order.  Unconditionally include item if filter matches - If the filter matches the item in the output series, the item will always be included in the output. No further filters will be applied to the data once this filter has matched. ClearPass Guest 3.9 | Deployment Guide Report Management | 345
