Datafeedr v4 import

I am trying to import watches from several jewellers using the datafeedr v4 plugin. When I do a basic search i.e Seiko or gents watch it brings back 0 results every time. Do I need to be more specific? I have tried various searches and different merchants with no results.
I am using UK Jewellers, do I need a different plugin as the min and max fields are in $

Any help would be greatly received
