Snippet pagination help

I recently downloaded garryn’s brilliant little snippet for the a to z listing. But I have an issue with the results. Basically under ’ALL’, I get a long list of all of my 200+ pages. Does anyone know how I can modify the snippet to show say 10 results per page?

Also, I have to manually add the child folder to my snippet call. With Ajaxsearch I could add the parent folder and the ’&depth’ parameter. Is this achievable to do on garryn’s snippet?

Any help greatly appreciated, I have tried to contact garryn but to no avail.
Thanks in advance
