I know I have contacts with no Country - this was something we came across recently when a colleague tried to use the proximity search and known contacts didn't appear. I've used Batch update to update a fair few I knew about, but when I use the Search Builder now to check for Contacts > Country > Primary > 'Is empty' or '≠' 'United Kingdom' and it comes back with nothing. But scrolling through the records, I can see there are still some records with no Country?
Am I not using the Search Builder properly or is there a bug? I'm using v4.4.13
