Filters tab

Use this tab to specify filters on dimensions or metrics. Filters can be simple or complex nested expressions. The filters are added to requests against Google Analytics to narrow down the result sets and reduce quota usage. All the options in the buttons are also available as context menu options of the filter tree.
