% users use The local Search machine (no replies)

Hi there,

I searched The forum nut i have not find what i was looking for.
I am looking for a widget which shows me the percentage of users that used the local search engine. At the current moment I make one segment. One shows me the number of users who has done more than one local search. now I know how many of all the have used the local search engine.
Could someone tell me if there is an easier way? Or maybe somebody is making this widget?

Thanx.
Peter
