Ruby on Rails

OK, and thanks a lot
using Kaminari.paginate_array(@geo_items)  solved my issue ...
I can get an array of items in which I can insert the distance from
the search point and sort the array on this distance..
I could not save this info into the item instance as it depends upon
each user's search ...

thanks a lot again !!
