Dashboard Filters
The Dashboard filters can be found on the Dashboard tab of the Details pane (Dashboard) on the Dashboard results page. It displays the filters that are being applied to the Dashboard.
Dashboard filters are applied to an entire Dashboard. If you add a filter to the Dashboard, it is added to the list of Dashboard filters, and the widgets in the Dashboard pane are updated. Filters are only executed on a widget if they are applicable. If the filter manipulates data that is not present in the Dashboard widget, the Dashboard widget remains unaffected.
