Filters, even if unselected, tell you just how your search results are distributed across various aspects of an interaction. The number of interactions that match a particular filter item with respect to the current query are displayed in parenthesis beside each item.

Any interaction that does not meet the above requirements has no score calculated and this is displayed as 'n/c'
