I think we should be able to search for a user based on a profile field, e.g. searching for people who's location contains UK or United Kingdom.
if they put the correct info in their profile ...Shame to have that information in user profiles and not be able to search on it. Just had a member in Italy who needed help posting so I went to vBulletin.com to look for someone in Italy to help him. I knew there were numerous Italian members, but I found no way to search on that field. Seems like it could be a nice feature.
we are not expecting XF to have this implemented on the first release anyway.xenForo definitely needs a more advanced search system but i won't expect it until Sphinx Search etc are implemented.
