results or for a view.
Place it on any $$viewtemplate or $$searchtemplate and pass the total to it.

Generate links in groups
place this script on a $$viewtemplate or $$searchtemplate
Input parameters:
total - the total number of documents in the view or search result
format - the format of the generated links
0 (or omitted) generates page numbers, ex. Previous | 1 | 2 | 3 |
Next
1 generates groups, ex.. Previous | 1 - 4 | 5 - 8 | 9 - 10 | Next
when you call the original view the URL should include two parameters:
&count will be used to calculate the intervals
&start must be the last parameter in the URL
defaults &count=30&start=1
place call to this function on the $$...template at the spot where you want
the links to appear
set the total passed to this function to TotalHits or
use @dbLookup to set it to the number of documents in the view
