In the following figure, the computed facet presents the total sales results per Salesforce opportunity stage. The numbers between the parentheses represent the number of opportunities for each stage. Refining the search, let's say to year 2011 with the Year facet, would update the Opportunity Stage facet to show 2011 opportunity stages.
The computed value can appear either on the right or below the caption of each facet item. A prefix and a suffix can appear before and after the value to help describe the meaning of the value.
Note: When it is not possible to compute a value, like the average number of pages for HTML documents, the value simply does not appear.
