How to customize the search category list in FacetApi module in Drupal-7 ?

I am using Drupal 7 facetapi and apachesolr module for search.. Right now if i search anything in my website, it lists all the nodes and the related categories/taxonomy terms like:

item1(2)
item2(5)
.
.
.
itemn(4).

I would like to customize this list by adding a total results count at the top of the list.so that the list looks like:
All results(n)
item1(2)
item2(5)
.
.
.
itemn(4)
Can anyone help with this?
