Is there a search term such as "Not US"?
The results of searches are always dominated by US sites. I live in Ireland and sites from Ireland, Europe generally, Australia, India, Middle East, are more relevant to me. Is there a search term such as "Not US"? I don't want to exclude America totally, just push those results further down the list.
That would be a question for your particular search engine of choice. Firefox doesn't searches, it displays them.
