The advanced filtering options open up new ways of leveraging the Analytics filters, by offering flexibility in how the values selected in each individual filter are applied to the metrics shown in the Dashboards.Selecting an item from the Advanced options dropdown is optional - each filter has a default option pre-selected which covers most cases and it matches the filter behaviour that was in place before the advanced filtering feature was made available.The options are:Any of the selected values (default) - Metrics are shown for conversations that have one or more of the filter values selected.None of the selected values - One or more of the values are not selected. A use case for this can be showing metrics for all conversations that are not tagged as "Spam". Any value - Applies for filters where the value can be empty. Selecting this option for the "Tags" filter for example, will show metrics for conversations that have some tag(s) attached, regardless of the value.All of the selected values - Metrics are shown for conversations that have all of the filter values selected. No value - Complementary to the option above, this will show metrics for conversations where no value is present for a given filter. A use case for this option would be to show metrics for conversations that have no queue assigned or no tag(s) attached.
